Revision 1.4 1999-01-21 11:54:25 peter
+ tools menu
+ speedsearch in symbolbrowser
* working run command
Revision 1.3 1999/01/12 14:29:40 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
Revision 1.2 1998/12/28 15:47:53 peter
+ Added user screen support, display & window
+ Implemented Editor,Mouse Options dialog
+ Added location of .INI and .CFG file
+ Option (INI) file managment implemented (see bottom of Options Menu)
+ Switches updated
+ Run program
Revision 1.31 1998/12/27 11:25:37 gabor
+ MatchesMask(), MatchesMaskList() and MatchesFileList() added
+ NameAndExtOf() added
Revision 1.3 1998/12/22 10:39:52 peter
+ options are now written/read
+ find and replace routines
