  Revision 1.11  1999-02-08 09:31:00  florian
    + some split heap stuff, in $ifdef TEMPHEAP

  Revision 1.10  1999/02/05 13:51:39  peter
    * unit name of FPSwitches -> FPSwitch which is easier to use
    * some fixes for tp7 compiling

  Revision 1.9  1999/02/05 13:06:28  pierre
   * allow cmClose for Compilation Dialog box

  Revision 1.8  1999/02/04 13:32:01  pierre
    * Several things added (I cannot commit them independently !)
    + added TBreakpoint and TBreakpointCollection
    + added cmResetDebugger,cmGrep,CmToggleBreakpoint
    + Breakpoint list in INIFile
    * Select items now also depend of SwitchMode
    * Reading of option '-g' was not possible !
    + added search for -Fu args pathes in TryToOpen
    + added code for automatic opening of FileDialog
      if source not found

  Revision 1.7  1999/01/21 11:54:11  peter
    + tools menu
    + speedsearch in symbolbrowser

      ones with ASCII < 32 ; entered with Alt+<###>) are interpreted always as
      ASCII chars and inserted directly in the text.
    + Added symbol browser
    * splitted fp.pas to fpide.pas

  Revision 1.3  1999/01/04 11:49:42  peter
   * 'Use tab characters' now works correctly
   + Syntax highlight now acts on File|Save As...

   * There was something very wrong with the palette managment. Now fixed.
   + Added output directory (-FE<xxx>) support to 'Directories' dialog...
   * Fixed some possible bugs in Running/Compiling, and the compilation/run
     process revised

  Revision 1.2  1998/12/28 15:47:42  peter
    + Added user screen support, display & window
    + Implemented Editor,Mouse Options dialog
