I _think_ what he wants is some kind of translation table between errno

No, I guessed wrong.  You are not dealing with errno at all but rather
VMS condition code to message lookup, which, as you've now discovered,
has already been fully answered.

 I was starting to think that it was about translating from
numeric value to symbolic name, which is a weird one.
 $ run moremsgfun
98962 = RMS$_FNF
