* harbour/include/hbapi.h
* harbour/source/vm/dynsym.c
+ added hb_dynsymIsFunction()
* harbour/source/rtl/filehb.c
* updated comment
* harbour/source/rtl/philes.c
* renamed HB_F_EOF() to HB_FEOF()
* harbour/source/rtl/scroll.c
* harbour/source/rtl/transfrm.c
* harbour/source/rtl/file.c
* formatting
* harbour/source/rtl/substr.c
* harbour/source/rtl/trim.c
% optimization
* harbour/source/rtl/typefile.prg
% use HB_ATOKENS() instead of static .prg function
* harbour/source/rtl/setkey.c
% optimization and protection aganst possible GPF when wrong array
is passed to HB_SETKEYSAVE()
* harbour/source/rtl/xhelp.c
! do not generate RT error when HELP symbol exist
(f.e. after PUBLIC HELP) but HELP() function doesn't
! keep reference in parametes passed by reference to __XHELP()
* use only PHB_DYNS instead of PHB_SYMB
* harbour/source/rtl/seconds.c
+ added WIN32 version borrowed from XHARBOUR
* harbour/source/rtl/trace.c
! protection against possible GPF when wrong parameters are passed
* harbour/source/rtl/samples.c
! protection against possible GPF when wrong parameters are passed
Warning! We have in this file few functions without HB_ prefix.
Some of them may create conflicts with future functions for TIMEDATE
items.
* harbour/source/rtl/inkey.c
+ added support for passing array with key codes as __KEYBOARD()
parameter, covered by HB_EXTENSION macro - this is xHarbour compatible
extension. I do not like it but we already had extension with numeric
parameters and probably it would be hard to remove it now and keep
__KEYBOARD() code clean so I decided to add support also for arrays
instead of creating new function and adding conditional code covered
by HB_COMPAT_XHB macro.
* harbour/source/rtl/setfunc.prg
* accept extended __KEYBOARD() parameters when HB_EXTENSION macro
is set.
