Combining what Vern offered with what Elvis offered, and testing it on
our V5 box, I found that I could set up a UNION VIEW.
But is there any way to index it, so that when opened through native RLA
(in this case, from C), it's sequenced according to first the "user
number" field, then Vern's library tag field?
In other words, the same effect as if I INSERTed the UNIONed SELECT into
a receiver PF that was keyed on those two fields (which is another
concept under consideration, but would have its costs).
Also under consideration is a non-SQL possibility, the use of a trigger
to slave a composite PF to all of the individual instance enrollment
files. (And God knows I have experience doing insanely complex things in
triggers, including slaving one file to another, and somehow getting
away with it!)
