You don't have to!  Just let the assertion dump core -- dbx (or
dbxtool, if you're on a sun) can debug the core dump to put you at
the statement where the core dump occurred.  I don't remember 
whether the VMS debugger will allow one to debug a core dump (or,
for that matter, whether VMS actually allows an assertion to dump
core); if it does, you might try this approach rather than modifying
the macro.

Hope this helps.
