$Log$
Revision 1.22 2000-05-10 13:40:19 peter
* -Se<x> option extended to increase errorcount for
warning,notes or hints
Revision 1.21 2000/02/09 13:22:50 peter
* log truncated
Revision 1.20 2000/01/07 01:14:23 peter
* updated copyright to 2000
Revision 1.19 1999/11/18 15:34:45 pierre
* Notes/Hints for local syms changed to
Set_varstate function
Revision 1.18 1999/09/07 14:03:48 pierre
+ added do_halt procedure
Revision 1.17 1999/08/05 16:52:53 peter
* V_Fatal=1, all other V_ are also increased
* Check for local procedure when assigning procvar
* fixed comment parsing because directives
* oldtp mode directives better supported
* added some messages to errore.msg
