      It can be used in the same context as multivalue macros
      or ... operator and converts array to list of parameters, i.e.:
         proc main
            local aValue, aIndexes

            aValue := { 1, { 2, 3, "abcde" } }

            ? "array:",    hb_valToExp( aValue )
            ? "indexes:",  hb_arrayToParams( aIndexes )

            ? "array[", hb_arrayToParams( aIndexes ), "] =>", ;
               aValue[ hb_arrayToParams( aIndexes ) ]
            aValue[ hb_arrayToParams( aIndexes ) ] += ":add"
            ? "array:",    hb_valToExp( aValue )

            aValue := { "test", aValue }
            aIndexes := { 2, hb_arrayToParams( aIndexes ) }
            ? "array:",    hb_valToExp( aValue )

               aValue[ hb_arrayToParams( aIndexes ) ]
         return

  * harbour/include/set.ch
  * harbour/include/hbset.h

    + added _SET_TIMEFORMAT
      The folowing modifiers are supported:
         hh - hours
         mm - minutes
         ss - seconds
         fff - fraction part of seconds
         p - 1-st letter from PM / AM signature. When used time is shown
             in 12 hour format otherwise 24 hour format is used
      ex: Set( __SET_TIMEFORMAT, "hh:mm pm" )
      default _SET_TIMEFORMAT value is "hh:mm:ss:fff"
    + added C function: char * hb_setGetTimeFormat( void );

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    + added support for timestamp constant values in the form:
         t"YYYY-MM-DD HH:MM:SS.fff"
      The exact accepted timestamp pattern is is:
         YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      i.e.:
         tValue := t"2009-03-21 5:31:45.437 PM"
      or:
         YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      with literal "T" as date and time part delimiters (XML timestamp
      format), i.e.:
         tValue := t"2009-03-21T17:31:45.437"
      The folowing characters can be used as date delimiters: "-", "/", "."
      if PM or AM is used HH is in range < 1 : 12 > otherwise
      in range < 0 : 23 >

  * harbour/source/compiler/complex.c
  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
  * harbour/source/compiler/harbour.yyh
    + added support for t"YYYY-MM-DD HH:MM:SS.fff" time stamp constant
      to compiler
    + added support for VFP datetime constant values:
         { ^ [ YYYY-MM-DD [,] ] [ HH[:MM[:SS][.FFF]] [AM|PM] ] }
      The following characters can be used as date delimiters: "-", "/".
      Dot "." as date delimiter is not supported.
      There is no limit on number of characters in YYYY, MM, DD, HH, MM,
      SS, FFF parts. Important is only their value. This is the format
      in semi PP notation:
         { ^ <YEAR> <sep:/-> <MONTH> <sep:/-> <DAY> [[<sep2:,>]
           [ <HOUR> [ : <MIN> [ : <SEC> [ . <FRAQ> ] ] ] [AM|PP] ] }
      In practice it allows to also parse xHarbour datetime constant
      values with compatible conditions though xHarbour support onlu "/"
      as date delimiter.
      NOTE: there is one important difference to VFP and xHarbour in
      decoding above format. In VFP and xHarbour when date part is
      missing then it's set by default to: 1899-12-30 so this code:
         { ^ 12:00 }
      gived the same results as:
         { ^ 1899/12/30 12:00 }
      Harbour does not set any default date value when timestamp
      constant value contains only time part.
      If you want we can change it for strict VFP compatiblity.
      Now this extension is enabled by default for testing. In the future
      it will be probably covered by HB_COMPAT_FOXPRO macro.

      compares date part in both values and then check if time part
      of timestamp value is 0.
    + added support for timestamp values in + and - math operations.
      The following rules are used in timestamp arithmetic:
         <t> + <t> => <t>
         <t> - <t> => <n>
         <t> + <n> => <t>

         <d> + <t> => <t>
         <t> + <d> => <t>
         <d> - <t> => <n>
         <t> - <d> => <n>
      When number is result or argument of timestamp operation then the
      its integer part is a number of day and fractional part is the time.

  * harbour/source/rtl/dateshb.c
    + added new .prg functions to mange date and timestamp values:

                                                            <tTimeStamp>
      HB_TTOS( <tTimeStamp> ) -> <cYYYYMMDDHHMMSSFFF>
      HB_STOT( <cDateTime> ) -> <tTimeStamp>
         <cDateTime> should be in one of the above form:
            - "YYYYMMDDHHMMSSFFF"
            - "YYYYMMDDHHMMSSFF"
            - "YYYYMMDDHHMMSSF"
            - "YYYYMMDDHHMMSS"
            - "YYYYMMDDHHMM"

            - "HHMMSS"
            - "HHMM"
            - "HH"
         Important is number of digits.
      HB_TSTOSTR( <tTimeStamp> ) -> <cTimeStamp> // YYYY-MM-DD HH:MM:SS.fff
      HB_STRTOTS( <cTimeStamp> ) -> <tTimeStamp>
         <cTimeStamp> should be in one of the above form:
            YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
            YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
         The folowing characters can be used as date delimiters: "-", "/", "."
         T - is literal "T" - it's for XML timestamp format
         if PM or AM is used HH is in range < 1 : 12 > otherwise
         in range < 0 : 23 >
      HB_HOUR( <tTimeStamp> ) -> <nHour>
      HB_MINUTE( <tTimeStamp> ) -> <nMinute>

      When @T is used without @D then only time part of timestamp value
      is formatted and return.
      When @D is used without @T then only date part of timestamp value
      is formatted and return.

  * harbour/source/rtl/tbrowse.prg
    + display timestamp values

  * harbour/source/rtl/philes.c
    + accept timestamp value as second parameter of HB_FSETDATETIME()
      function

      SEEK and SEEKLAST with date value when active index is on
      timestamp positions to 1-st or last record where date part
      of indexed timesamp value is equal.
      Settings scopes to date values when active index is on timestamp
      value reduce the visible record range to these ones which have
      date part of timestamp value in the range of dates values used
      for scopes. It possible to mix date and timestamp values in scope
      and set one scope to date value and the second to timesamp.

  * harbour/source/rdd/sdf1.c
  * harbour/source/rdd/delim1.c
    + added support for exporting timestamp fields

    + updated HB_ZipFileCreate( hZip, cZipName, tDateTime, cTime, ... )
      functions to optionaly accept timestamp value in 3-rd parameter
      instead od dDate, and cTime in 3-rd and 4-th parameters.
    + updated HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
      to return timestamp value in 3-rd parameter instead of date value.
      TODO: Please think about removing 4-th parameter from:

            timestamp values usable

         contrib/hbole/ole2.c
         contrib/hbwin/win_ole.c
            add support for timestamp values in OLE

         contrib/rddado/adordd.prg

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
    * moved from RTL to HVM

      copy of SET structure for child threads
    * hidden HB_SET_STRUCT declaration - 3-rd part code must not access it
      directly. Dedicated hb_set*() functions should be used instead.
    + added new function:
         BOOL hb_setSetItem( HB_set_enum set_specifier, PHB_ITEM pItem )
      which allow to change some set by 3-rd party code.
      TODO: not all SETs can be changed yet - if someone have a while
            then please add code for missing ones.

  * harbour/include/set.ch
  * harbour/include/hbset.h
    + added _SET_CODEPAGE which works like _SET_LANGUAGE giving common

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/include/hbapicdp.h
  * harbour/source/rtl/cdpapi.c
    - removed global code page variable: hb_cdp_page and moved

    + added new function hb_cdpID() which returns current code page
      character ID
    + added new functions hb_vmCDP() and hb_vmSetCDP() to get/set

    * changed HB_DYNS declarations for MT mode. In MT mode HB_DYNS does
      not contain area and memvar handles which are moved to thread
      local HVM stack
    + added array for thread local memvar and area handles to HVM stack
    % eliminated global continues array with all memvars and detached locals
    % changed HB_IT_MEMVAR to use pointers to HB_ITEM directly - it resolve
      synchronization problems in MT mode and should also improve the speed
      and reduce memory usage. It should be well visible in applications which
      uses lot of detached locals.
    - removed hb_memvarsInit() and hb_memvarsFree() - they are not necessary
      now because we do not longer use array with all allocated memvars
      and detached local and private stack initialization is made
      automatically
    + added internal functions hb_dynsymGetMemvar()/hb_dynsymSetMemvar()
    + added hb_memvarGetValueBySym() for debugger
    * moved PRIVATE variable stack to HVM stack
    * eliminated all static variables in memvars module

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/source/rtl/fserror.c
    * moved IO errors to HVM stack
    + added special IO error handling which works without HVM stack
      It allows to use hb_fs*() functions without allocated stack
      by 3-rd party threads.

  * harbour/source/rtl/filesys.c
    * moved hb_fsCurDir() to HVM stack with special handling to work
      with HVM stack like IO errors

  * harbour/source/rdd/workarea.c
    * allocated RDD node array in bigger peaces to reduce later RT
      reallocations in MT mode. If user want to add dynamically more
      then 64 RDDs then it should synchronize this operation himself.

  * harbour/source/rdd/wacore.c
    * moved WA list, current WA, default RDD and neteer() flag to HVM stack

  * harbour/include/hbdefs.h
    - removed HB_HANDLE declaration

  * harbour/include/hbapi.h
    - removed HB_VALUE structure - it's not longer used due to different
      memvar handling
    * updated hb_struMemvar to new memvar handling
    * replaced hb_vmIsLocalRef() and hb_memvarsIsMemvarRef() with
      hb_vmIsStackRef() which respect multiple stack and new memvar
      and static structures and location in GC mark pass.

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/source/vm/hvm.c
    + added support for thread specific data located on HVM stack
      Now it's possible to allocate static variables which are
      local to thread. Such variables are allocated on HVM stack
      and automatically destroyed. To declare new TSD variable use:
         HB_TSD_NEW( <name>, <size>, <init>, <destruct> )
      <name> - name of variable which holds TSD handler
      <size> - size of TSD are which has to be allocated
      <init> - init function, executed when new TSD is allocated by thread
               (thread access given TSD 1-st time). This function receives
               void * pointer to allocated area.
      <destruct> - destructor function executed when HVM stack is destroyed
      f.e.:
         static HB_TSD_NEW( s_scrData, sizeof( HB_SCRDATA ),
                            NULL, hb_xSaveRestRelease );
      To initialize dynamically allocated TSD variable use:
         HB_TSD_INIT( <name>, <size>, <init>, <destruct> )
      Pointer to TSD can be accessed using hb_stackGetTSD( &<name> )
      where <name> is name of variable which holds TSD handler, f.e.:
         PHB_SCRDATA pScrData = ( PHB_SCRDATA ) hb_stackGetTSD( &s_scrData );
      See source/rtl/xsavescr.c as an example
      It's also possible to test if data has been already allocated for
      current thread by:
         hb_stackTestTSD( &<name> ) => pData
      it works like hb_stackGetTSD() but return NULL if current thread data
      has not been allocated yet.

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c

    + added new PCODE HB_P_THREADSTATICS
    + added support for static variables which are local to thread:
         THREAD STATIC <varname [:= <exp>], ...>
      They work like normal static variables but each thread operates
      on its own copy.
    * added protection against possible double call to hb_xfree()
      It can happen due to wrong marking expressions as used by bison

  * harbour/include/hbapi.h
  * harbour/include/hbvm.h
  * harbour/source/vm/hvm.c
    + added hb_vmThreadInit()/hb_vmThreadQuit() functions - they initialize
      HVM for calling thread so it can execute .prg code and call HVM
      functions. They can be used by 3-rd party code threads.
    + added hb_vmUnlock()/hb_vmLock() functions which informs that
      thread will not operate on HVM structures for some time allowing
      to execute single thread only processes like GC.
    + added hb_vmThreadQuitRequest() which sends stop request to given
       thread
    + added hb_vmWaitForThreads() which stops main thread execution waiting
      for other threads
    + added hb_vmSuspendThreads() and hb_vmResumeThreads() used be GC
      to stop all HVM threads before mark/swap scan
    + added linked list of HVM stacks
    + added hb_vmTerminateThreads() used by main HVM thread in QUIT state
    * moved EXIT procedures execution from QUIT request to HVM QUIT state
      in MT mode. It may effects some non structural code which tries to
      access private variables in EXIT functions but it's much cleaner
      and understandable for user. Please remember that we guaranties
      that ALWAYS code in BEGIN SEQUENCE is _always_ executed even after
      HVM QUIT request just like destructs. Personally I think that we
      should move EXIT procedures execution also in ST mode.
    * changed startup and cleanup code for new internal structures
    * changes startup and cleanup code for MT mode
    % removed some redundant HB_ITEM type settings
    ! eliminated non MT safe code which was using reference counters
      without protection

  * harbour/common.mak
  * harbour/source/vm/Makefile
  + harbour/include/hbthread.h
  + harbour/source/vm/thread.c
    + added C level functions to manage threads and synchronization objects
      See hbthread.h for detail description. They are based on PTHREAD API
      and PTHREAD documentation can be used as reference. I intentionally
      keep this list small for easier multiplatform porting.
      Now they have been implemented for PTHREADS (POSIX threads supported by
      many different OSes), MS-Win32/64 and OS2. The OS2 version is not tested
      at all. I do not even know if it can be compiled so please make tests.
      I used Internet resources and some part of xHarbour code as documentation
      for OS2 MT API. It should be quite easy to add other platforms if necessary.
      Harbour core code needs non recursive mutexes, conditional variables and
      TLS for one pointer. If platforms does not support conditional variables
      (f.e. MS-Win or OS2) then they can be emulated using multistate semaphores.
    + added .prg functions to manage threads and synchronization objects:
         hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
         hb_threadJoin( <pThID> [, @<xRetCode> ] ) -> <lOK>
         hb_threadDetach( <pThID> ) -> <lOK>
         hb_threadQuitRequest( <pThID> ) -> <lOK>
         hb_threadWaitForAll() -> NIL
         hb_mutexCreate() -> <pMtx>
         hb_mutexLock( <pMtx> [, <nTimeOut> ] ) -> <lLocked>
         hb_mutexUnlock( <pMtx> ) -> <lOK>
         hb_mutexNotify( <pMtx> [, <xVal>] ) -> NIL
         hb_mutexNotifyAll( <pMtx> [, <xVal>] ) -> NIL
         hb_mutexSubscribe( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
         hb_mutexSubscribeNow( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
      The function list should give similar to xHarbour API but they are not exactly
      the same and except of hb_mutex*() functions which should replicate xHarbour behavior.

  + harbour/source/vm/vmmt
  + harbour/source/vm/vmmt/Makefile
    + added hbvmmt library to GNU make builds.
      Non GNU make builds should be updated.

  * harbour/contrib/gtwvg/gtwvg.h
    - removed #include <comctl32.h> - my MinGW and MinGW/CE instalations do

      covered by #if version checking.

  * harbour/source/vm/dynsym.c

    * modified code to be MT safe and improved speed of some operations
    * added MUEXT protection for global dynamic table access

  * harbour/include/hbapi.h
  * harbour/source/vm/garbage.c
    * changed to work with MT HVM
    * changed to work with new memvar structures and thread local static and
      memvar variables
    * added MUEXT protection for linked block lists
    + added parameter to hb_gcCollectAll() which will force GC activation
      in MT mode by temporary suspending all executed threads.
    + added logical parameter to HB_GCALL() functions which is passed to
      hb_gcCollectAll()

  * harbour/source/vm/fm.c
    * added MUEXT protection for FM statistic module
    * added MT protection for reference counters. For platforms
      which supports atomic incrmenetation/decrementation (f.e.
      Interlocked*() functions in MS-Win) such operations are
      used. For other it's MUTEX protection. It gives MT safe
      readonly access for HVM complex variables without user
      synchronization. The MUTEX protection can cause some speed
      overhead so it's good to define MT safe version of
      HB_ATOM_INC()/HB_ATOM_DEC() in hbthread.h if given platform
      has them. Now they are defined only for Windows. For other
      platforms We can define can define them in assembler for some
      most popular CPUs in the future.

  * harbour/source/vm/classes.c
    * changed class definition array. Now it keeps pointers to class
      structures.
    * In MT mode allocated at HVM startup big enough array for class
      definitions to avoid later RT reallocations. It effectively eliminates
      MUTEX synchronization for class structure access.
    * protect by MUTEX code for new class creation

  * harbour/source/debug/dbgentry.c
    * eliminated hbvmopt.h and direct accessing to HVM structures

  + harbour/tests/mt/mttest06.prg
  + harbour/tests/mt/mttest07.prg
    + added some demonstration/test small MT programs written
      using Harbour language. Some of them can be also compiled
      by xHarbour but xHarbour does not pass any of my tests in
      real multi-CPU machine so do not expect they will work
      correctly.

   Harbour threads needs OS threads support. Each Harbour thread is directly
   mapped to OS thread. It's not very efficient on some older system where
   cost of thread creation and/or task switching is very expensive but it
   should not be bigger problem for modern OS-es which can support threads
   in practice nearly in user space only.
   I haven't touched Harbour function calling convention which comes from
   Clipper. It means that we do not pass pointer to VM to each functions
   like CLIP or xBase++. To resolve the problem I have to use thread local
   storage (TLS) where such pointer is kept. If platform does not support
   TLS then it can be emulated by us. Anyhow the speed of accessing TLS
   data and extracting HB_STACK poitner is critical for performance.
   Some compilers depending on used hardware and OS give native support
   for TLS (f.e. __thread keyword in GCC/BCC or __declspec( thread ) in MSVC).
   This should give optimal performance. On other Harbour uses TLS functions
   like TlsGetValue() (MS-WIN) or pthread_getspecific() (PTHREAD) are used.
   OS2 gives quite interesting TLS functionality which seems to be quite fast
   though it will be interesting to know how it is iplemented internally for
   real multi CPU machines (if it depends on CPU exception then the
   performance will be bad). We need TLS only for one pointer to HB_STACK
   structure.
   I haven't added any tricks like HB_THREAD_STUB in xHarbour to reduce
   the cost of TLS access. If it will be necessary for some platform the we
   can add it.
   Except TLS Harbour threads needs OS support for non recursive mutexes or
   critical sections and conditional variables. If platforms does not support
   conditional variables (f.e. MS-Win or OS2) then they can be emulated using
   multistate semaphores. I intentionally didn't create code which may need
   recursive mutexes. The non recursive ones are often faster and some
   platforms may not support recursive mutexes so they will have to be
   emulated by us.
   Harbour uses reference counters for complex variables. It means that even
   readonly access to complex item causes internal write operations necessary
   to increment/decrement its reference counter. To make such readonly access
   MT safe we have to make incrementation and decrementation with result
   checking atomic. By default it's done by mutex inside vm/fm.c but some
   platforms have native support for atomic inc/dec operations, f.e. 
   Interlocked*() functions in MS-Win. If they are available then such
   functions should be used to not reduce the performance by mutex call
   very often used functions. For many CPUs it should be quite easy to
   implement such atomic inc/dec functionality in assembler. F.e. for
   GCC and x86@32 it may looks like:

      static __inline__ void hb_atomic_inc32( volatile int * p )
      {
         __asm__ __volatile__(
            "lock incl %0"
            :"=m" (*p) :"m" (*p)
         );
      }

      static __inline__ int hb_atomic_dec32( volatile int * p )
      {
         unsigned char c;
         __asm__ __volatile__(
            "lock decl %0"
            "sete %1"
            :"=m" (*p), "=qm" (c) :"m" (*p) : "memory"
         );
         return c == 0;
      }

   and then it's enough to define in hbthreads.h:
      #define HB_ATOM_INC( p )    hb_atomic_inc32( ( volatile int * ) p )
      #define HB_ATOM_DEC( p )    hb_atomic_dec32( ( volatile int * ) p )

   Probably I'll make it for some most popular CPUs in the future.
   In Harbour each thread which wants to call HVM functions have to allocate
   it's own HVM stack. It's done hb_vmThreadInit(). The HVM stack is freed
   by calling hb_vmThreadQuit(). This functions can be called also by 3-rd
   party threads if they want to call HVM functions or execute .prg code.
   Calling HVM functions without allocated stack will cause GPF.
   I moved most of static variables to HVM stack to make them thread
   local. But some of them like FS errors have their own alternative
   copy which is used when thread does not allocate HVM stack. It allows
   to use hb_fs*() functions without HVM stack but programmer have to
   know that error codes return by hb_fs*Error() functions can be
   overwritten by other threads which also didn't allocated HVM stack.
   To execute garbage collector scan and mark pass it's necessary to
   stop other HVM threads. Otherwise the scan may give false results.
   It's also possible to not stop threads but protect with mutex all
   operations on GC items but it will probably cause performance reduction
   and will force some other modifications. Maybe I'll implement it
   in the future.
   I didn't use any OS level thread KILL or CANCEL calls. All HVM threads
   have to be cleanly removed without any resource leaks.
   QUIT command terminate only calling thread. If main (startup) HVM
   thread call QUIT then it sends QUIT request to all existing threads.
   In QUIT state ALWAYS statements and destructors are executed.
   New thread is created by:
      hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
   The returned value is a pointer to internal thread structure which
   can be used in JOIN or DETACH operations. Each thread should be Joined
   or DETACHED to avoid resource leaks. If programmer does not store
   <pThID> or all instances of <pThID> are destroyed then thread is
   automatically detached. I do not know clear method of thread detaching
   in OS2. If some OS2 users knows it then plase update vm/hbthread.c.
   When thread terminates then all locked by this thread mutexes are
   released.
   Each thread uses its own memvars (PRIVATEs and PUBLICs) and work areas.
   When new thread is created then it inherits from parent thread:
      - code page
      - language
      - SETs
      - default RDD
   error block is initialized to default value by calling ERRORSYS()
   and PUBLIC variable GetList := {} is created.
   The following objects are initialized to default value:
         - error block
         - math error handler and math error block
         - macro compiler features setting (hb_setMacro())
           or move them to SETs.
   We can think about inheriting them. It's also possible to add
   inheriting of all visible memvars but I do not know it's good
   idea.

   Compilation and linking:
   For MT mode HVM library should be compiled with HB_MT_VM macro.
   GNU make automatically creates hbvmmt library which should be
   linked with Harbour MT programs instead of hbvm.
   Non GNU make files should be updated.
   If given compiler support TLS then you can try to set HB_USE_TLS
   to force using native compiler TLS support. Now it's enabled by
   default only for BCC. For Linux and GCC builds it may depend also
   on used GLIBC version. In older system there is no TLS support
   at all or TLS works only for shared binaries so I haven't enabled
   it. If you will test some other compiler then please add default
   native TLS support for them in hbthread.h
   Users using hb* scripts can simply use -mt switch when they want
   to create MT program, f.e.:
      hbmk -n -w3 -es2 -mt mttest01.prg

   There are still some minor things which should be done but I'll
   do them later. Current state seems to be fully functional.
   The most important and still missing is our own file lock server
   for RDD synchronization in POSIX systems. Kernel internally
   recognize POSIX locks by PID and file i-node - not PID and file
   handle. It means that the same file open more then once by one
   process shares locks. Because POSIX locks can be overwritten
   then we do not have any synchronization between aliased workareas
   or threads using the same table in *nixes. We have to make
   synchronization ourselves. I'll create such lock server ASAP.

   Please test and enjoy using Harbour threads.

  + harbour/source/vm/hashes.c
  + harbour/source/vm/hashfunc.c
    + added hash items, f.e.:
         local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
         ? h2[ "a" ], h2[ "b ]
    + added support for DYNAMIC function declaration - it allow to define
      functions which are lately bound at runtime, f.e.:
         /*** t01.prg ***/
         dynamic func1
         proc main()
         local h:=__hrbload("t02.hrb")
         ? func1()
         return

         /*** t02.prg ***/
         func func1
         return "Hello!!!"

    % use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
      it reduce memory usage, FUNCALL is much smaller then FUNCTION
    % use symbol scope bits when possible instead of making some linear scan
    + added new enumarator message: __ENUMKEY - it allow to access
      key value when hash item is base enumerator value, f.e.:
         proc main()
         local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
         heval( h, { |k,v,i| qout( k, v, i ) } ); ?
         for each v in h
            ? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
                       valtype(v:__enumBase())
            v += 0.123
         next
         ? ;heval( h, { |k,v,i| qout( k, v, i ) } )
         return
    + added C level hb_hash*() functions
    + added support for full HASH item cloning and updated array cloning
      to also clone nested hashes - please note that xHarbour does not do
      that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
      _DOES_NOT_ clone _ANY_ nested items.

  * harbour/include/hbextern.ch
    + added hash functions HB_H*()
    * changed INET*() functions to HB_INET*()
    + added hash functions H*() and socket functions INET*() when
      HB_COMPAT_XHB is set

  * harbour/include/hbtypes.h
    + added missing HB_EXTERN_BEGIN / HB_EXTERN_END

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    ! added protection against automatic word concatenation in some cases
    ! fixed preprocessing expressions when match marker matches ';' token

  * harbour/source/rtl/Makefile
  + harbour/source/rtl/itemseri.c
    + added functions for item serialization: HB_SERIALIZE() and
      HB_DESERIALIZE() - these function are not binary compatible
      with xHarbour functions with the same names but make very
      similar job with the exception to serialization of codeblock
      and object variables - Harbour does not allow to serialize
      codeblocks and serialize objects as arrays.
      In most cases these functions can replace the xHarbour ones
    + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
      by HB_COMPAT_XHB macro - this functions are only for compatibility
      with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
      dummy function which returns first parameter and HB_DESERIALNEXT()
      is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
      use them.

  * harbour/source/rtl/hbinet.c
    * changed INET*() functions to HB_INET*() and enable them for default
      build
    + added INET*() functions wrappers covered by HB_COMPAT_XHB macro

  * harbour/source/rtl/hbrandom.c
    + added HB_RANDOMINT() - xHarbour compatible

  * harbour/source/rtl/len.c
    + added support for HASHes

  * harbour/source/rtl/valtype.c
    + added support for HASHes
    + added set of HB_IS*() functions - they are a little bit faster then
      calling VALTYPE( v ) == <cVal>
    - removed HB_ISBYREF() - this function cannot longer work, it was using
      a Clipper incompatible anomalies in passing variables by reference I
      fixed so it has to stop to work. If it will be realy necessary to
      implement HB_ISBYREF() function then please inform me - it will have
      to be done at compiler level or with some much deeper HVM stack
      checking.

  * harbour/source/vm/extend.c
    ! fixed hb_extIsArray() and hb_extIsObject() to work well with
      parameters passed by reference.
      Please note that now hb_extIsArray() return TRUE only for pure arrays
      not object values.

  + harbour/contrib/tip/url.prg
  + harbour/contrib/tip/utils.c
    + added TIP library - code borrowed from xHarbour



   Please test - a lot of above code is not well tested, also some peaces
   were written over year ago for different things (f.e. serialization for
   NETRDD) and now I collected them and committed.
   The TIP library was not tested at all. It can be compiled but I cannot
   say if it works - I hope that people familiar with it can make necessary
   test and fixes.
   It's also not the final version of low level HASH item code. I'm working
   on more efficient structure which uses binary tries but I cannot say when
   I'll finish it (maybe in this weekend or maybe in next year) so I committed
   working version now even if I'm not happy with overall performance (BTW
   not worser then in xHarbour)

      optimizer
    * chaned a little bit WITHOBJECT syntax.

      are empty line between WITHOBJECT and END

    ! added protection against cyclic references in arrays
    * eliminated action parameter from hb_vmRequestReenter() /
      hb_vmRequestRestore()
    * moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
      for future MT HVM version
    + added internal item structure hb_struRecover - it's not real item
      but this structure is used to keep information about BEGIN SEQUENCE
      data - it reduce HB_STACK usage
    + added support for ALWAYS clause in BEGIN SEQUENCE
      The syntax is:
         BEGIN SEQUENCE
            <code>
         [ RECOVER [ USING oErr ] ]
            <recoverCode>
         [ ALWAYS ]
            <alwaysCode>
         END [ SEQUENCE ]
      It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
      inside <code> or <recoverCode> some new exceptions like RETURN,
      BREAK or QUIT will appear.
      Please note that when the following code is executed:
         BEGIN SEQUENCE
            <code>
         ALWAYS
            <alwaysCode>
         END
      (without RECOVER clause) then BREAK exception inside <code> is not
      recovered, <alwaysCode> is executed and then BREAK exception is
      passed to outer BEGIN SEQUENCE. This is the same semantic as
      used in TRY / [ CATCH ] / FINALLY / END
      Those of you who prefer to use TRY / CATCH / FINALLY / END instead
      of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
      source code:
         #command TRY               => BEGIN SEQUENCE
         #command CATCH [ oErr ]    => RECOVER [ USING <oErr> ]
      and:
         errorBlock( {|oErr| break( oErr ) } )
      Though instead of 'break( oErr )' I suggest to use some small function
      which will support some basic recovery/substitute operations like in
      default errorsys() and LockErrHandler() to not break existing code
      which may depends on the default behavior.
      If you want I can add direct support for TRY / CATCH / FINALLY / END
      but I'm not sure it's really necessary.
      Please note also that in Harbour ALWAYS code is execute even for QUIT
      excpetion.
      When <alwaysCode> is executed current exception is stored and restored
      when is finished. If new exception appears inside <alwaysCode> then
      restored exception depends on the priority in the following order:
         QUIT     // highest priority
         BREAK
         RETURN
      If both exceptions have the same priority and contain additional value
      (error object in BREAK or return value in RETURN) then the recently set
      one is restored. It's similar behavior to destructor code.

  * harbour/source/common/hbstr.c
    * moved one character length string table (hb_szAscii) from hvm.c
      to use it also in compiler and preprocessor

  * harbour/source/compiler/ppcomp.c
  * harbour/source/pp/ppcore.c
  * harbour/source/pp/pplib.c
    * tuned error messages to be more Clipper compatible
    % use static strings from hb_szAscii

  * harbour/source/rtl/alert.prg
    * use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
    ! some minor fixes
      TOFIX: we have to also use GTI_ISCTWIN or add window allocation
             to standard GT drivers to be Clipper compatible when CTWIN
	     is used - In Clipper Tools ALERT() works in differ way then
	     the standard one. It creates separate window box to display
	     data, supports SETKEY(), etc. I'll think about adding some
	     extended support for ALERT() and similar operations (f.e.
	     separate debugger windows) to GT API so it will be also
	     possible to overload standard alert() command by GUI message
	     box in GTGUI and similar GT drivers.

  * harbour/contrib/odbc/odbc.c
    ! removed #include <malloc.h> - it should not be used with new C
      compilers
      I think that we should replace this library with hbodbc from xHarbour.

      statement
    * changed PCODE generated of ++,--,+=,-=,...
      Now left side expression is evaluated _ONLY_ once and when object
      messages are used it's guarantied that exactly the same object
      variable will be used. It also fixes some problems which exists
      in Clipper. This optimization is enabled by -kh flag (by default)
      and can be disabled with -kc.
    % optimize ald macros in ++,--,+=,-=,... operations
    * add automatically "_" prefix when macro message is used in assignment
      context, f.e.:

      + added support for 16MB codeblocks and strings
      ! removed macrocompiler limitation for jumps range
      ! fixed GPF when more then 255 local variables is used and added
        support for 2^15 locals
      ! removed all strtok() functions
      % added optimization for all +=, -=, *=, %=, ^=, **= operations
        when left side of expression is variable or array item
      % added optimization for all +=, -=, *=, %=, ^=, **= operations
        when left side of expression is object method and updated ++, --
        for new code. It's still disabled until we will not add support
        for late evaluated reference items to HVM
      ! fixed a[++i]++ and similar operations (a[++i]*=2, ...). Now ++i is
        executed only once. It's not Clipper compatible but it was in
        TODO note in source code. It can be disabled by -kc option
      * finished support to xHarbour like #pragma TEXTHIDDEN(1)
      ! fixed local add int optimization when PARAMETERS used after
        optimization changed local variable number over 255
      ! fixed GPF trap when in HB_P_<op>EQ PCODEs when executed for
        direct values

     Implemented in HVM and PCODE generation, the compiler has to be
     modified yet to use them.
   * changed last parameter in hb_codeblockGetRef() - I'd like to have
     all variables in hb_struRefer structure in one place: hb_itemUnRefOnce()
     for easier modifications in the future.
   * replaced in hb_struRefer 'itemsbase' with 'array'.
   + added hb_arrayGetItemRef() to create references to array elements.
     Such reference updates array reference counters.

* harbour/include/hbapi.h
    * moved HB_STACK_STATE declaration from hbstack.h to hbapi.h
      it's covered by _HB_API_INTERNAL_ macro so it should not
      effect 3-rd party code
    * modified hb_struSymbol structure:
         LONG stackbase
      replaced by:
         PHB_STACK_STATE stackstate
      this modification allows to keepadditional information bound with
      function call stack accessible from different HVM modules.
      Now it's used by memvars code to keep/update PRIVATE variables
      stack pointers. I plan to store in HB_STACK_STATE structure
      information additional information for classes code like super
      casting or instance variables offsets in new OOP model I'm working on.
      It can be also used by debugger code to retrieve some informations
      about executed functions without active updating by main HVM loop.
    + added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
      variables
    + added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
      offset so PRIVATE variables created in current function/procedure
      will not be removed when it returns
    - removed hb_memvarsRelease() and hb_memvarValueNew()

  * harbour/include/hbstack.h
    + added hb_stackClearMevarsBase() - helper function for hb_memvarsClear()
      clears PRIVATE stack offsets in executed functions
    * changed to static offset from int to long - in different places we
      were using int or long in HVM so I cleaned the HVM code to always
      operate on the same type

  * harbour/source/vm/estack.c
    * set/restore PRIVATE stack base offset in hb_stackNewFrame()/
      hb_stackOldFrame()
    * updated for new HB_IT_SYMBOL structure

  * harbour/source/vm/hvm.c
    ! removed setting/restoring PRIVATE stack base offset in hb_vmExecute()
      It make code like:
         eval(&("{||VAR:=1}"))
      Clipper compatible
    * updated for new HB_IT_SYMBOL structure
    * changed order of execution exit procedures for clean memvars removing
      and future destructors execution. I'll describe it better when I'll
      add destructors.

  * harbour/source/vm/memvars.c
    ! fixed CLEAR MEMORY - now this function should be safe in Harbour
      It's not exactly compatible with Clipper because I intentionally
      didn't replicated some Clipper bugs like possible memory corruption.
    + added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
      variables
    + added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
      offset so PRIVATE variables created in current function/procedure
      will not be removed when it returns
    ! fixed releasing PUBLIC and PRIVATE variables which were passed by
      reference and are still active on HVM stack or in codeblocks as
      detached locals (see: hb_memvarDetachDynSym())
    * modified hb_memvarFindSymbol() to be more Clipper compatible
    % optimized hb_memvarRelease() to operate or PHB_DYNS instead of
      string comparison and not make linear dynamic symbol scan for
      PUBLIC or not existing symbols
    - removed hb_memvarReleasePublic()

  * harbour/include/hbvmpub.h
  * harbour/include/hbxvm.h
  * harbour/source/compiler/gencc.c

  * harbour/source/vm/itemapi.c
  * harbour/source/vm/pcount.c
  * harbour/source/vm/proc.c
  * harbour/source/vm/pvalue.c
    * updated for the above modifications

  * harbour/source/rtl/memvarbl.prg
  * harbour/source/rtl/menuto.prg
    * use __mvEXIST( cMemvar ) instead of __mvSCOPE( cMemvar ) > HB_MV_ERROR
      __mvEXIST() is much faster function

  * harbour/source/rtl/type.c
    * execute hb_memvarUpdatePrivatesBase() after macro type checking.
      This should not be necessary but we are not Clipper compatible here
      and this is work around for difference in our TYPE() implementation.
      Clipper for:
         ? TYPE("VAR:=1")
      create PUBLIC variable VAR when [x]Harbour PRIVATE one.
      Should we try to make it Clipper compatible?

   The above should fix problems reported with memvars. We are not 100%
   Clipper compatible but unlike in Clipper we cannot break VM internals
   using some operation on references to memvars and detached locals
   and/or RELEASE.../ CLEAR MEMORY. This modifications should be intensively
   tested. If you will find any problems with current code please inform me.
   I'd like to hear your opinions about memvars created by TYPE() (see above).
   Should we change it? It may not be very easy operation - we will have to
   change macro compiler and add new PCODE for that.

      and covered by internal API macro. Should not be used by 3-rd
      party code because we may change them in the future or even remove.

  * harbour/source/vm/garbage.c
    + added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
      functions. These are also internal function which corresponds to the

    * changed hb_vmProcessSymbols() to return address of register symbol
      table. For normal code it's the same address as given in parameter
      so it does not break backward binary compatibility.
    + use new code for operator overloading
    * changed FOR EACH to dynamically check iteration scope in
      hb_vmEnumNext()/hb_vmEnumPrev() and remove max number of iteration
      stored on HVM stack

      workaround for possible GPF. I'd like Ryszard will chose the final
      version

      functions (macros)

  * harbour/source/vm/runner.c
    * synced with xHarbour

  * harbour/utils/hbtest/rt_misc.prg
   * added overloading "=" operator. Now "==" and "=" can be overloaded
     with different methods

   All names I used for new functions/macros can be changed. Please look at
   it and if you will some better propositions then we can use it.
   hb_vmProcessSymbolsExt() is added but not used yet.

  * harbour/source/compiler/hbdead.c
    + added support for dead code elimination in functions which uses
      SWITCH ...; CASE ...; ...; END syntax

  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/hbfix.c
    ! fixed optimization for HB_P_PUSHLOCALNEAR and HB_P_POPLOCALNEAR.
      It was a long existing bug not reported so far because 0, 1 and 2
      PCODEs uses only one BYTE and bad PCODE tracing in hbfix.c didn't
      caused bad side effects as long as number of locals in function
      was smaller then 768. Now for functions HB_P_PUSHLOCAL and
      HB_P_POPLOCAL is used and later changed to NEAR version in hbfix.c
      if possible.

  * harbour/source/compiler/hbfix.c
    * join sequential jumps to optimize constructions like:
         while ...
            ...
            if ...
               exit
            endif
         enddo

  * harbour/source/compiler/hbdead.c
    * remove HB_P_END PCODE also at the and of function if is repeated
      just before, f.e. in code like (source/rtl/color53.prg):
         Function RADGRDEFCO( cColor )
            if isdefcolor()
               Return applydefau( cColor, "W/N", "W/N", "W+/N")
            Else
               Return applydefau( cColor, 3, 1, 4)
            endif
         Return nil
      Now such redundant constructions like above are fully stripped by
      compiler anyhow if someone has time and think is important then can
      clean also this .prg code.

  * harbour/source/compiler/hbpcode.c
  * harbour/source/vm/hvm.c
    + added support for generating real C code not PCODE in .c files.
      Now with  -gc3 Harbour will generate .c files with real .c code
      which is later compiled to real machine code.
      I left PCODE only for code block definitions though it's also
      possible to have even code block compiled to machine code but
      we will have to add a flag to codeblock structure which will
      be checked at runtime and proper method of execution in EVAL
      will be chosen. If you think it's worth of afford then I can
      add it too in some spare time.
      The final binaries are noticable longer then the one which has
      only PCODE but they are faster. The speed improvement depends
      on type of operations. The pure Clipper code which does not
      execute any external time consuming C functions compiled with
      -gc3 is from 10% to 50% faster.
      The side effect of generating pure machine code is also harder
      recompilation but it does not mean that is impossible. If sth
      can be executed by some machines (virtual or hardware) then it
      can always be decompiled by definition.
      This modification opens door for farther optimization, f.e. when
      we will have fully working strong type support then we can add
      using native .c types.
      In fact this module is PCODE to .c translater not part of compiler
      and can be used as separate module to translate generated PCODE,
      f.e. .hrb files.
      Maybe in the future we will change the compiler to generate meta
      code not directly PCODE and it will be possible to make optimizations
      on this meta code which will depend on selected output type:
      VHM PCODE, C code, .NET code, etc. but at this moment adding support
      for .c compilation directly into compiler will make the compiler code
      too much complicated for me - IMHO it's better to invest time into
      clear separation to FRONT_END->REAL_COMPILER->BACK_END
      Please make test with your code. I rebuild whole Harbour code with
      -gc3 set in HB_FLAGS in harbour/config/rules.cf and all seems to
      work correctly. hbtest returns exactly the same results.
      I also made tests with my programs and they work correctly but
      I had to define actions for all PCODEs and it's possible that made
      some typos in some of them which are very seldom used so your tests
      will be very important.
