    * restored support for old hb_inLine() syntax
    + added support for hb_inLine() to new PP. It can be enabled by
      -kI compiler switch. It's disabled by default.
      The new hb_inLine{} syntax is:
         [ <exp> ] hb_inLine [ ( [<params,...>] ) ] { [ <c_code> ] } [ <exp> ]
      <c_code> can contain new line characters.
      Nested hb_inLine{} in <params,...> is not supported. If you think
      it's important I can add it in few lines.
      This version does not break any valid Clipper syntax, hb_inLine is
      not reserved word and hb_inLine can be repeated many times in the
      same line. F.e. this code can be properly preprocessed and compied if
      you disable in compiler old hb_inLine() syntax and enable the new one
      by -kcI Harbour compiler switch:

         proc main()
         local hb_inLine := " (var) "
         ? hb_inLine{ hb_retc("inLine"); } + hb_inLine(" parameter ") {
              hb_retc( hb_parc( 1 ) );
              } + "!" + hb_inLine + hb_inLine() { hb_retc( ":-)" ); } + ;
           hb_inLine() + "{}"
         return
         function hb_inLine()
         return " func() "

      So from user point of view this version have real "inline" syntax.
      To be clear: I'm not a fun of any C inline extensions. They works
      only when we use .c code as compiler backend so the code which uses
      them cannot be used in .hrb files and any other format we will add
      in the future which do not support later C code compilation. F.e it
      will not work in compiler integrated with HVM or with .NET
      Anyhow if someone finds it useful then I think that it should be
      properly implemented. This is the reason I added the new version.
      The old one I left only for backward compatibility. It breaks any
      code which uses hb_inLine keyword can be used only once in a line
      and it does not have "inline" so IMHO it should not be enabled by
      default.
      I would like to hear your opinion about default compiler switches:
         1. should we disable both: hb_inLine() and hb_inLine {}
         2. should we disable hb_inLine() and enable hb_inLine {}
         3. should we disable hb_inLine {} and enable hb_inLine()
         4. should we enable both: hb_inLine() and hb_inLine {}

    + New PP code written from scratch. It works in similar way to
      Clipper PP even the error codes are replicated. The code is MT
      safe does not have any limitation on size of preprocessed code,
      line, etc. It's also Clipper compatible lexer. It means that
      we do not longer need FLEX or SIMPLEX which can be replaced
      by new PP after some small modifications. Anyhow I haven't
      decided to make it myself. I would like to agree with with the
      rest of developers. I will be very happy if such modifications
      will be done by someone else, Ryszard?
      Meanwhile I current PP join on output the line tokens and give
      the string line to FLEX/SIMPLEX. It does not have any sense and
      all FLEX/SIMPLEX limitations are still existing. Ryszard, even
      if we keep it then I hope you can remove at least FLEX line buffer
      and use the one returned from PP.
      Because string tokens in parsed line are converted to text which is
      later once again decoded to tokens by FLEX I had to introduce new
      string format which supports embedded string delimiters. I chose
      modified version of xHarbour extension with escaped strings e"<sting>"
      so now FLEX understand such strings and decode them like C escaped
      strings. It means that you can use them also in the .prg code f.e.:
         outstd( e"Hello\n\rWorld" )
      The new PP is also noticeable faster. You should see the difference
      compiling long files. The build in PP rules are generated automatically
      by ppgen program created from source/pp/ppgen.c
      I had to add to GNU source/pp/Makefile these two lines:
         pptable.c : ppgen$(EXE_EXT)
         	./ppgen$(EXE_EXT) $(TOP)$(ROOT)include/hbstdgen.ch -opptable.c -q
      Sth like that will have to be done also in non GNU make system.
      Now Harbour can be compiled only using GNU make.
      Marek can you update non GNU make files? I would like to leave this
      modification to you or other developers who can test it.
      It was quite big modification and I do not believe that I haven't
      make any mistakes but I hope that in few weeks I'll fix any reported
      bugs and it will resolve any PP problems.
      TODO:
         * error messages
           create one common list of errors and warnings and keep it
           in common library. PP and compiler can still generate different
           errors with the same number. It can be confusing for the users
           and hard to document and add i18n translations.
           If possible we should also try to keep Clipper error numbers.
           In new PP code I added Clipper error numbers but I cannot use
           them until compiler code is not updated.
           We should aslo remove the ctype passed to error functions and
           hack with first character in warning messages and use only
           error number. The codes from 1000 to 1999 should be warnings
           where range 1000:1099 is activated by -w, 1100:1199 by -w1,
           1200:1299 by -w2, etc. 2000:2999 are errors and 3000:3999
           fatal errors. All compiler functions which generate an error
           should expect that error function will not stop the compiler
           but return and cleanly finished their job. It's necessary for
           MT support in compiler and making compiler part of some other
           programs which may still work and compile different source code.
         * FLEX/SIMPLEX
           remove them at all and add some final pass to PP to create
           more precise tokens for grammar parser or at least add better
           integration to remove some redundant code and existing limits.
         * hb_inLine() support - it's broken in new PP but as I can see
           it was never working correctly. I can add a hack to PP to support
           hb_inLine() but I'm not sure it's worth to do. Maybe in few days.

  + harbour/include/std.ch
    + added new std.ch. It was created without using Clipper's std.ch.
      It's quite possible that some rules are wrong and should be fixed
      so please help. Anyhow I created a set of programs based on new PP
      code generating all possible combinations of different commands I
      collected from different source code, documentation and match patterns
      of rules I was adding to new std.ch and then I was comparing .ppo
      files generated by Clipper and Harbour so I do not expect any bigger
      problems then some minor typos. I had to introduce some modifications
      in spacing as workaround for FLEX/SIMPLEX which cannot properly decode
      text preprocessed by Clipper after stringify.

  * harbour/utils/hbpptest/pretest.prg
    * updated for new PP
      It reports 16 wrong translations but some of them are valid
      and some others are caused by escaped string e"..." (one of hack
      for FLEX/SIMPLEX support)
      I also had to remove all spaces in comparison the results
      because they were not Clipper ocmpatible at all. Ryszard please
      look at it.

* harbour/include/hbclass.ch
    + added validation for class data names. As additional preprocessor
      rule to not use <!marker!>

  * harbour/include/hboo.ch
  * harbour/source/rtl/tclass.prg
  * harbour/source/vm/classes.c
    + added delegate messages

  * harbour/include/hbstack.h
  * harbour/source/vm/arrays.c
  * harbour/source/vm/estack.c
  * harbour/source/vm/hvm.c
  * harbour/source/vm/proc.c
    + added startup symbol to hb_stack. It gives very good stop
      condition for all procedures which trace stack calls and
      resolves the problem with hb_stack.pBase which was never
      pointing to valid function/procedure symbol when no symbol
      was put on HVM stack. Now after hb_stackInit() the first
      item is allocated for "hb_stackInit()" symbol so hb_stack.pBase
      is always a pointer to valid function/procedure symbol.
    * changed the guard condition for buggy code in hb_stackPop()
      and similar code from:
         hb_stack.pPos < hb_stack.pItems
      to:
         hb_stack.pPos <= hb_stack.pBase
      The old condition was generating usable error message only in the
      startup function. In deeply called functions it was only waste of
      CPU time on one of the most often call functions. Before it was
      activated internal stack structures were corrupted.
      If we were leaving for many years without really working stack
      underflow protection then maybe we should think about disabling
      it at when HB_STACK_MACROS are used and keep it only in real
      stack functions for HVM developers. Single protection in
      hb_stackOldFrame() I've just added is enough for basic C code
      validation.
      I created the second version of stack macros without it in
      hbstack.h but I would like to hear other developers opinion.

* harbour/include/hbclass.ch
    * most of the rules rewritten
    ! fixed some wrong rules and general cleanup
    + added additional code validation
    ! fixed compilation of more then one class in single file.
      Now it's even possible to declare all classes at beginning of
      single file and then implementing their methods in any order
    ! fixed using static classes and classes
    ! fixed compilation without <ClassName>_ prefix in method names
    + added support for HB_CLS_NO_DECORATION macro which disable
      adding <ClassName>_ prefix to method names - this macro is
      set by default when HB_SHORTNAMES is set.
    + added support for declared parameters validation - it can be
      disabled with HB_CLS_NO_PARAMS_ERR and I had to disable it
      by default due to problems with our preprocessor.
      Ryszard seems that our PP has serious problems with decoding
      directives when there is no space between symbol and some other
      non symbol character. I had to add some workarounds and even
      introduce buggy rules to make it working. Please look at it.
      You can remove #define HB_CLS_NO_PARAMS_ERR from hbclass.ch
      and try to rebuild Harbour core code to see the problem.

  * harbour/include/hboo.ch
  * harbour/source/vm/classes.c
    + added support for new primitive message: HB_OO_MSG_PERFORM

  * harbour/source/rtl/tclass.prg
    - removed <lPersistent> parameter from HBClass messages and
      internals data. Persistent is supported as scope bit and
      separate variable was redundant.
    - removed stripping of () from message names. Here is not a place
      to fix wrong preprocessor rules.

  * harbour/utils/hbtest/rt_class.prg
    * use: METHOD PROCEDURE ... CALSS ...
      instead of: PROCEDURE ... CALSS ...
      The first version is preferable syntax.

  * harbour/source/debug/dbgtmenu.prg
  * harbour/source/rtl/checkbox.prg
    ! fixed some parameters in method declaration - global cleanup
      will have to wait for preprocessor fixes

   Hi all,
   Please make test with current hbclass.ch code.
   I hope that I haven't broken too much things ;-) but I rewrite
   from scratch most rules and it's possible that I missed sth or
   made some stupid typos. Current version is much shorter and should
   be easier to updated. For sure I've intentionally changed one thing.
   CLASSDATA was ignoring SHARED attribute and always created shared
   class variables. Seems that it was long existing typo but the fix
   may interact with already existing code which needs SHARED class
   variables but does not use SHARED clause in CLASSDATA declaration.
   In such case please update it and add missing SHARED.
   Also in the end of CLASS declaration we have:
      [ ; #translate Super( <SuperClassN> ): => ::<SuperClassN>: ] ;
      [ ; #translate Super( <SuperClass1> ): => ::<SuperClass1>: ] ;
      [ ; #translate Super(): => ::<SuperClass1>: ] ;
      [ ; #translate Super: => ::<SuperClass1>: ] ;
      [ ; #translate ::Super : => ::<SuperClass1>: ]
   These rules introduce very serious bug - they are breaking supercasting
   in code which makes sth like:
      ::super:super:super:msg
   or in any other code which sends SUPER message to some other class
   objects. I will have to remove them. At least the last three ones.
   There were some other things I wanted to write about but it's too late
   and I'm to tired - sorry. If you will have any question please ask. if
   you will notice some problems with current rules please inform me.
2006-10-04 00:33:00 +00:00
Ryszard Glab
64509ea871 + added support for passing methods as macro
eg:
         o:&send()
         o:&send.end()
         o:&(expr)()
         o:&var++
         o:&var := 0
         o:&(expr)++
         WITH OBJECT obj
            ++:&var
            :&var += :&(var2+"oo")
         END

   NOTICE:
   For simple assigments (=,:=), compound assignments (+=,-=,*=,/=)
   and for pre/post increment operators( ++,--) the macro should
   evaluate to a symbol that starts with underscore '_'.
     To access a variable the macro should evaluate to a symbol
   with no '_' char.

  * harbour/include/hbapierr.h
  * harbour/source/rtl/errorapi.c

      function which can be executed from different .prg functions.

    * changed symbol name in hb_symEval from __EVAL to EVAL and modified
      hb_symEval registration method to not register hb_vmDoBlock as global
      function. Having PHB_DYNS address for "EVAL" in hb_symEval.pDynSym
      allows to eliminate some strcmp() when we are looking for EVAL public
      symbol.

    % use hb_symEval.pDynSym
    + added support for object variable type scope checking like in Class(y).

    ! fixed bug in real codeblock scoping which was exploited by

    * changed ACCESS messages to ASSIGN ones when object item
      reference is created for proper READONLY scope checking.
      The reference to object variable can be created only when
      caller has sufficient ASSIGN privileges.
    + added FRIEND CLASS and FRIEND FUNCTION support.
      It's enough to add class definition:
         FRIEND CLASS <classFunc1> [, <classFuncN> ]
      and/or:
         FRIEND FUNCTION <FuncName1> [, <FuncNameN> ]
      and all methods of given class or given function will be able
      to access private variables.
      Warning!!! Friends cannot access overloaded non virtual methods.
                 This feature is available _ONLY_ for real class members.
    + added MODULE FRIENDLY to class definition. It causes that all other
      functions and classes defined in the same .prg module will have
      friend privileges. In such way works xHarbour and there is now way
      to disable this "feature" what is IMHO bug. In Harbour programmer
      has to explicitly enable it (until he will not change / add new
      preprocessor rule and set it as default ;-)). Syntax:
         CREATE CLASS .... MODULE FRIENDLY

  * harbour/source/vm/classes.c
    * removed hb_objGetpMethod() - I hope it's not longer used
    * added real codeblock scoping.
      In Clipper there is no information where the codeblock where
      created and what priviladges/scopes it should has.
      Class(y) to resovle this problem when codeblock is executed scans
      the HVM stack for the nearest method call and takes scopes defined
      for this method. It's a workaround which allow to break standard
      access rights though seems reasonable when it's not possible to
      store information where the block is created. I've added to block
      item structure information about class and method where code block
      was created so we can use the exact method priviladges.
      Now Harbour classy code can work exactly like Class(y) when compiled
      with -DHB_CLASSY_BLOCK_SCOPE and with real code block scoping when
      compiled with -DHB_REAL_BLOCK_SCOPE. I set the second (real code
      block scopes) as default. If you think we should be strict Class(y)
      compatible here then please inform me and I'll change default setting.

    ! Do not add unnecessary class variables for the same class when

    ! Do not add unnecessary initialization class and instance variables
    + added support for non virtual messages
    + added support for static and casted scoping
    + super cast messages added automatically. They are used to dynamic
      recalculation of instance are offsets and to avoid multiple inheritance
      of the same class so please do not overload them or you will have as
      result something what we have before recent modifications in the
      instance and class data area. Just simply run tests/clsccast.prg
      and tests/clsicast.prg compiled with current CVS code and last
      release code or with xHarbour and compare the results.
      Also Class(y) does not pass these tests and I do not know if any
      other dynamic OOP model in xbase languages can properly address it.
      BTW maybe I should add RT error when .prg code will try to delete
      or overwrite class cast message. For me it seems to be reasonable
      and what's your opinion?
    * make hidden class members non virtual by default. It can be disabled
      by compiling classes.c with -DHB_VIRTUAL_HIDDEN but IMHO keeping
      HIDDEN members as virtual causes that they are not really HIDDEN
      because subclasses can simply overwrite them. It also means that
      it's not possible to create class with some private data and
      methods which will never interact with any subclass code created
      by other programmers where name conflict can appear. So one of
      the most important OOP features is missing in such case.
      See tests/clsnv.prg as an example for non virtual hidden members.

  + tests/clsicast.prg
    + added test code for proper instance area allocating and casting

  + tests/clsccast.prg
    + added test code for proper class data allocating and casting

  + tests/clsnv.prg
    + added test code for non virtual hidden class members

   Now we should be able to create and class model even replicate the
   static one like in C++ using current class engine which still fully
   supports dynamic bindings. It consumes less memory and due to much
   more efficient hashing it should be faster then it was though some
   other minor optimization can be add and I'll plan to make them in
   some spare time.
   The item type verification in assignment is still missing. I'll add
   it when I'll collect some statistic informantion I'd like to ask
   [x]Harbour users. I need these information to tune some internal
   structures where I can balance between speed and memory allocation
   to statistically optimal form.

   Marek asked me to add passing object datas by reference and I'll do
   that but I'd like to ask Ryszard to add support for:
      @<oVar>:<message>
   to compiler. I'll implement all other HVM modifications. If you can
   please also add support for:
      <oVar>:&<cMsgName>[(...)]
   For this we do not need any HVM modifications or new PCODEs.
   We are supporting xBase++ macro list compilation in:
      cList:="1,2,3"
      x := aVar[ &cList ]
      aVar:={ &cList }
      func( &cList )
   But we do not support:
      <oVar>:<message>( &cList )
   IMHO it looks ugly. If we have this syntax for function call then we
   should also support it in message sending.
   Ryszard can you make necessary compiler modifications?
   I'm also thinking about adding support for variable parameters
      func myfunc(...)
      [...]
      return xVar
   In few cases it will help to encode some function much more efficient
   then now.

   I'll add Class(y) compatible functions used in class(y) header files
   so it will be possible to use original class(y) .ch files in Harbour
   though it will not be the most efficient because we have @func() operator
   which gives better performance then using codeblocks. Anyhow classy
   create separate meta class for each class with CLASS members and
   <clasName>() function always return such meta class object so for full
   Class(y) compatibility we need to generate differ .prg code.
   But all such modifications now can be done on preprocessor and
   .prg level and they will not need .c code modification.
   We should make them to give user interface for our new OOP features.

   Now I'm waiting for reports about any problems with current classy
   code.

* harbour/include/hbapi.h
  * harbour/source/vm/hvm.c
  * harbour/source/vm/codebloc.c
  * harbour/source/vm/arrays.c
    * moved static base offset from hb_struBlock structure
      to HB_CODEBLOCK structure
    + added hclass member to hb_struBlock - it will be used in
      the future for checking codeblock scope in classy so we will
      real scope checking also for messages sent from codeblocks.
    - removed supercast and superoffset members from hb_struArray
      structure.

  * harbour/include/hbclass.ch
    * added class(y) like
         @:<MessageName>([<MsgParams,...>])
      send operator. It's not exactly the same as in class(y) where
      this operator is hardcoded to executing function directly,
      needs method name instead of message name and is linked statically.
      In Harbour this operator uses message name so can be used also for
      instance variables and make dynamic casting to the class from which
      current method is inherited. In short words sending messages to @:
      instead of :: causes that they work like non-virtual messages in
      C++ mode.
      If you do not use the same method body in different classes
      then you can also use explicitly self casting:
         ::<myclass>:<msgname>[(...)]
      and it will be a little bit faster

  * harbour/include/hboo.ch
    + added: HB_OO_MSG_ASSIGN, HB_OO_MSG_ACCESS,
             HB_OO_MSG_CLSASSIGN, HB_OO_MSG_CLSACCESS
      They should be used insted of HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
      This resolves problems with name conflicts when we were detecting
      type of message (ACCESS/ASSIGN) by checking the first character
      in message name. F.e. now it's possible to create exported instance
      variable called __WithObject and it will be used in all WITH OBJECT
      statement instead of the base object value. It's simple and effective
      WITH OBJECT overloading.
      I kept backward compatibility for HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
      but I strongly suggest to update code to use new constants.
    + added HB_OO_MSG_REALCLASS

  * harbour/source/rtl/objfunc.prg
  * harbour/source/rtl/tobject.prg
  * harbour/source/rtl/tclass.prg
    * use HB_OO_MSG_[CLS]{ASSIGN,ACCESS} instead of HB_OO_MSG_[CLS]DATA

  * harbour/source/rtl/tclass.prg
    + added REALCLASS message to creted classes - it's used for @: operator

  * harbour/source/vm/classes.c
    * updated for above modifications
    * calculate instance area offset in supercasting dynamically - it
      will allow to eliminate multiple instance area allocating when
      in the inheritance tree the same class exists more then once and
      also quite easy add support for non-virtual messages.
    ! fixed GPF in __CLSINSTSUPER() class function generate HVM exception
    % do not inherit unaccessible inline blocks
    * some other minor optimization, fixes and code cleanups

  * harbour/source/rdd/usrrdd/usrrdd.c
    ! fixed HB_TRACE message

  * harbour/source/rtl/errorapi.c
    ! generate internal error if ErrorNew() function does not return an object

* harbour/include/hbset.h
   * harbour/include/set.ch
   * harbour/source/pp/pptable.c
   * harbour/source/rtl/set.c
     + Added Set( _SET_DEFEXTENSIONS, <logical: .T./.F.> )
       Default value is .T. (CA-Cl*pper compatible). If set to .F.,
       Harbour runtime/RDD code will never attempt to add a
       default extension to the filename arguments. Commands/functions
       where this setting makes a difference are:
       - SET ALTERNATE TO / Set( _SET_ALTFILE_, ... )
       - SET PRINTER TO / Set( _SET_PRINTFILE_, ... )
       - Set( _SET_EXTRAFILE, ... )
       - SAVE TO / __mvSave()
       - RESTORE FROM / __mvRestore()
       - LABEL FORM
       - REPORT FORM
       - COPY TO ... DELIMITED
       - COPY TO ... SDF
       - LIST / __dbList()
       - USE / dbUseArea()
       - dbCreate()
       - SET INDEX TO / ordListAdd() (not yet implemented)
       - __HRBLOAD(), __HRBRUN()
     ; Notes:
       - From now on, it possible to create/load files using the
         above functions/commands which have no extension. This
         might be desirable in a few platform and/or situations.
         For example on Win32, it's possible to directly print
         to a shared Windows printer queue, using these commands:
             lOldValue := Set( _SET_DEFEXTENSIONS, .F. )
             SET PRINTER TO \\myserver\myprinter
             Set( _SET_DEFEXTENSIONS, lOldValue )
         Or, it is possible to open a dbf file which has no extension:
             dbUseArea(.T., NIL, "dbf_filename_with_no_extension", "w_DATA", .F., .F.)
       - Compiler is (of course) not affected by this setting.
       - Preprocessor (PP) lib flavour is not affected by this setting.
       - Support is not full in the RDD code yet.

    ! fixed bug in wrong integer negating, f.e.:
         proc main(); local i:=0; i-=-32768; ? i; return
    ! fixed PCODE generated for +=, -=, /=, *= expressions when right side

* harbour/include/hboo.ch
    + added HB_OO_CLSTP_PERSIST and HB_OO_MSG_INITIALIZED

  * harbour/include/hbapi.h
  * harbour/include/hbvmpub.h
  * harbour/source/vm/dynsym.c
    % changed HB_HANDLE hArea to USHORT uiArea to reduce HB_DYNS size.
      RDD code internally uses USHORT as area number so it's not
      necessary to keep it as HB_HANDLE value.

  * harbour/source/vm/arrays.c
    * modified internal static function name

  * harbour/source/vm/itemapi.c
    + added missing HB_TRACE in hb_itemClone()

  * harbour/source/vm/classes.c
    ! moved initialization values to separate structure not bound with
      methods. We can inherit the same method names from more then one
      object so we will store only the first one but we are inheriting
      whole instance area which is accessible with super casting (last
      fixes) so we have to properly initialize it even if methods does
      not exist. This modification also fixes some possible memory leaks.
    % replaced bIsPersistent by HB_OO_CLSTP_PERSIST in uiScope in method
      definition
    ! added basic parameter validation to __CLSADDMSG() to avoid some
      possible strange behavior at runtime when broken messages are
      defined.
    * updated __OBJHASMSG() and __OBJSENDMSG() to accept SYMBOL items
      too (@funcName()). Using symbol items it faster then strings.
      Also added support to use non array parametes. F.e. now
         __OBJHASMSG( {||NIL}, "EVAL" )
      returns TRUE
    * some other fixes, reduced memory consumption and speed optimizations

+ harbour/source/codepage/uckam.c
    + added missing in my previous commit file

  * harbour/include/hbvmpub.h
  * harbour/source/vm/dynsym.c
    + added USHORT uiSymNum to HB_DYNS structure - I will need it for MT
      as index for thread local HB_DYNSYM values for MT version in the
      future but now I use it as perfectly efficient continuous hash
      value for all symbols. Of course PHB_DYNS address is also perfectly
      good hash value and in classes code can be used but it does not
      guaranties that all messages will cover well whole 16bit area used
      as message pool without dynamic bucket size modification.

  * harbour/source/vm/classes.c
    * changed hashing method. Now it uses really unique base hash key
      values which can cover whole 16 bit area so mathematically it's
      not be possible to break it by any combination of method names
      as long as our dynamic symbol table will be limited to 2^16 symbols.
      It still consumes more memory then necessary and I'll change it in
      the future but it's much less then before.
      The BUCKET size is smaller (4) and all calculations are done only
      with bit shifts so it should be also faster.
    * use ULONG instead of USHORT to calculate maximum number of methods
      to avoid possible overflow problems if it reach 2^16 (rather
      impossible in normal application - it will have to create more then
      2^15 symbols)
    ! some other fixes and code cleanup

  * harbour/source/vm/hvm.c
    * minor modifications

      Vojtech many thanks.
      We will have to fix our CDP code to work well with characters
      with the same wight - now sorting with such codepages does not
      work correctly, f.e. in CSISO:
        CHR(65)+CHR(204) > CHR(65)+CHR(201)
      but:
        CHR(65)+CHR(201) >= CHR(65)+CHR(204)
      as you can see comparison depends on string order:
        s1 > s2 but not s2 < s1
      It means that such codepages cannot be used in any sorting
      systems like indexes until we will not fix internal CPD logic.
      Alexander can you look at it?
      If not then please inform me and I'll work on it in some spare
      time.

* 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

  * 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.
