Re: EVAL-CORR

I was looking at the code I wrote last year. Well, last week actually, but it seemed a long time ago. There I was, like the next developper called upon todo the maintenance, and I said to myself, "Why has he put EVAL-CORR? - that would suggest that the two DS were not the same". So, I went back to a move, as in my OP but then asked myself if was safe, hence my question.

I just had reason to look at eval-corr - turns out it is
smart enough to do a mass move if the DS' have all the same
fields. Nice!

But it does the field-at-a-time if there is a difference,
either in order or name, I guess.

Remember that an eval will do a left-to-right (or r-l)

move. It does

not respect field names et al.

This is some code to read a file and copy the row to

create a new one.

I notice that when compiling, the DS obtained from LIKEREC

( MyFormat :

*INPUT ) is not the same as LIKEREC ( MyFormat : *OUTPUT ).

Therefore, in the example below, is it safe to use RecordOut =
RecordIn or is EVAL-CORR necessary?
Thanks.
