Re: Record blocking optimization

Tony-
Not exactly, unless both files are keyed or sorted in the same order
and you are using matching records logic.

Similar to Rob, I've written exactly 1 matching record logic program in my 24 years as an RPG developer.

I'm sure that some of the REAL programmers on this list have samples!!!!

For a little more on matching record logic, see:

Are you aware of this jewel of a penalty that David Gibbs concocted for violating the rules of the RPG400-L mailing list <lol>?
