Mike Levin <mlevin@presto.cs.tufts.edu> had problems with starting a
background process (DECWindows application):

You probably want to use
	$ SPAWN/NOWAIT/INPUT=NL:  <your_command_here>

A process started this way will *not* be affected by ^C and ^Y.

There are a few more similar cases in VMS, where you need an unobvious
non-default qualifier for typically desired operation.
Some examples from my daily experience:
	$ submit /NOPRINT
	$ copy /NOCONCATENATE
	$ set host /RESTORE
	$ type /PAGE
	$ directory/size =ALL
	$ cc/list /SHOW=BRIEF
      privileged:
	$ backup <file> <file> /OWNER=PARENT
	$ initialize <fixed_disk> /HEADERS=<bignum>

Maybe one could make a FAQ topic out of this?
