Quoting from the VMS V4.4 Release Notes, section 3.3.5.2 (page 3-41):
The debugger now uses the VAX/VMS Screen Management Facility
(SMG) to implement screen mode. If your program also calls
SMG routines, and you debug it with the debugger running on the
same terminal, there will probably be interference between
your program and the debugger.
To avoid this problem, debug the program using two terminals.
The technique is described in Appendix D of the VAX/VMS Debugger
Reference Manual.
A better workaround is to do your debugging on a VAXStation. If properly
setup (i.e. a logical name needs to be defined, see the VWS Release Notes),
then the debugger screen will pop up in a separate window so you end up
with two VT220 windows, one for your application and one for the debugger.
Neato!
