Working in C, how do you get the RMS$_CODE symbol for any given error
number as returned from any operation? I use strerror() to get an
interpretation but it does not include said symbol.

exit(rms_return_number); will print it out so I know it must be possible.

 Can you explain what was missing in the previous answers you received
so the authors of those answers can clarify them if needed ?

I _think_ what he wants is some kind of translation table between errno
values and VMS condition codes.  For example, starting with errno of
ESRCH and getting to RMS$_RNF or vice versa.  I'm not aware of any such
table, and if there were, it wouldn't be a one-to-one  mapping.
