Cool! The structure wrapper must be needed by VMS for some reason,
then. I was just worried that it was something significant that was
glossed over in the docs. Well, that makes it a lot easier for me! I'm
very pleased to have my fears proved groundless. Thank you very much!

A couple of other questions come to mind, with passing pointers -
first, since ADRS1 and ADRS2 are pointers to my records, if I
dereference them and modify non-key fields in them in my user_equal
routine, it would indeed change the actual record, correct? I know the
answer in C, but am not sure in BASIC, i.e., is my function accessing a
pointer to the actual record, as does C, or is it a pointer to a local
copy of the record? The latter doesn't seem likely.

And if I can, would doing so make the sort choke? I don't see why,
because I'm not changing keys, but you never know. I'll check this out
empirically.
