Martin,
True, you might need mv-handling subrs for mv fields. Which are always
fun. (I hate to concede that correlatives might actually be better at
something, but I do wish there were a way to write a variation of an
I-descriptor where you could code single value logic, with the value
looping implied, like *cough* correlatives do. There, I said it. It's
in writing. On the internet.)
But, Martin, the method does NOT fail if you have multiple
I-descriptors. It did on PI, but not on UV. UV uses seperate @-buffers
for each I-descriptor, insulating i-descriptors from each other.
I don't think the method works on UD at all.
Tongue firmly in cheek, where it still hurts from biting it praising
correlatives: The downside is you can't do fancy things like pass
information between I-descriptors via @-buffers like you could on PI.
That kind of i-descriptor hotshot programming was excellent for job
security because no one else had a hope of deciphering it. When I was
young I explored the outer limits before settling on a reasonable mix of
when to write a subroutine and when to do everything in native
I-descriptor line 2. I wonder how long it took Lynden to undo some of
that after I left? (Be gentle now, Rick.)
George's remarks about presorting are spot-on.
For breakpoints: @NB, & TOTAL() with keyword CALC are your friends.
They should be in everyone's RetrieVe & uniQuery repertoire.

Simpler than my approach but it fails with multivalues or with queries that
have other I-types in them.
