An earlier effort, in RPG III, had to work with the limit of an array. Been
years since I attempted this. Point was that I could not fit all the Detail
record FUNCTIONS into a record for sorting. Likely, the size limit has been
eased over the years. But, a record length of 10000 just to accommodate all
possibilities seemed a bit excessive.

Quoting Charles Wilt <charles.wilt@xxxxxxxxx>:

I'm confused...you say "There are several instances where the Detail
records for one Master record are the same as
the Detail records for another Master record."

Then you say, "Still was a manual process to examine how closely the
records matched."

How could they be the same but not match?

In the past, I have tried to locate these by using RPG and building big
variables containing the FUNCTION, then sorting them.  Still was a manual
process to examine how closely the records matched.

Can SQL do this?
