When I said 'hack' I meant the ugly code that I had to create to make
the trick work--the idea of having to put a dummy parameter into the
function call in the basic program in order to make it compatable with
the subr call in the i-type.

Ditto! :-) One might add faster and more stable triggers and built-in
input timing.

Here's some interesting info and an ugly hack--in unidata.
It seems completely wrong to me (UV in Prime flavour)
Apparently, the keywords SUBROUTINE and FUNCTION are interchangable

MYFUNC is globally cataloged

I tend not to use a FUNCTION unless I really need it for the syntax. It
helps me to remember that even when calling a function you can change
any of the passed variables - not just the return variable (just like a
subroutine). For some reason I didn't think a function could do that,

Previous posters have pretty much covered the ground. UniVerse (and, I suspect
but can't be certain about, UniData) functions are implemented as subroutines,
with the first argument position on the stack reserved for the return value
which is a DATUM. It can even be a file variable or
You can use functions in I-descriptors (via the SUBR function only) because the
mechanism that reserves the first position on the stack for functions is
exactly the same mechanism used by the SUBR() function.
You can not use custom functions directly as functions in I-descriptors because
