[fa.info-vax] VMS DEBUGGER

I'd like to share a cute thing that happened to our system yesterday.
Users of my system started to complain that the DEBUGGER didn't work.
The problem showed itself as follows:
	$ FORTRAN/DEBUG prog
	$ LINK/DEBUG prog
	$ RUN prog
	%RMS-F-FNM, error in file name
	$
After a desperate search for why this was happening, I looked at the
system logical table and saw an entry for DBG$INPUT but none for
DBG$OUTPUT. Typing "ASS/SYS SYS$OUTPUT: DBG$OUTPUT" cured the problem.
Although a file name error is the reason for killing the DEBUGGER, it
seems as if a stack dump would have been better (what happens when a
user has an open statement referencing a file that doesn't exist w/no
error traps).
