	VMS had a whole slew of "no error" status values (essentially all
positive odd integers were "success", but different values carried
additional information. Even integers were errors [I forget if positive or
negative were "warnings" vs "error"])

	True, the simplest was "1", which just carried "success -- no
additional details" and "0" was "unspecified failure".
