Initial revision
|
|
|
|
Revision 1.5 1998/03/10 01:17:15 peter
|
|
* all files have the same header
|
|
* messages are fully implemented, EXTDEBUG uses Comment()
|
|
+ AG... files for the Assembler generation
|
|
|
|
Revision 1.4 1998/03/02 01:48:07 peter
|
|
* renamed target_DOS to target_GO32V1
|
|
+ new verbose system, merged old errors and verbose units into one new
|
|
verbose.pas, so errors.pas is obsolete
|
|
|
|
Revision 1.3 1998/02/13 10:34:37 daniel
|
|
* Made Motorola version compilable.
|
|
* Fixed optimizer
|
|
