  $Log$
  Revision 1.9  1999-02-10 09:55:43  pierre
     + Memory tracing if compiled with -dHEAPTRC
     * Many memory leaks removed

  Revision 1.8  1999/02/08 09:30:59  florian
    + some split heap stuff, in $ifdef TEMPHEAP

  Revision 1.7  1999/02/05 13:51:38  peter
    * unit name of FPSwitches -> FPSwitch which is easier to use
    * some fixes for tp7 compiling

  Revision 1.6  1999/01/21 11:54:10  peter
    + tools menu
    + speedsearch in symbolbrowser
    * working run command

  Revision 1.5  1999/01/12 14:29:31  peter
    + Implemented still missing 'switch' entries in Options menu
    + Pressing Ctrl-B sets ASCII mode in editor, after which keypresses (even
      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
