Anyone else feel like jumping in?

Hi Rob,

Actually, I'm not chaining/reading into a data structure - my file is
externally defined, and I'm chaining/reading into the record format.

My question is: Since I have an externally-defined data struture using the
same file, when I chain/read into the record format don't the fields end
up also being "in" the data structure? And since they're "in" the data
structure, aren't they contiguous?

If the answer to one or both of these questions is "no", then I've been
seriously misunderstanding what is going on (which is possible - that' s
why I'm asking the question! ;-)

But if the answer is "yes", then I don't see what LIKEREC gives me, except
that now I can chain/read directly into the data structure. Not meaning to
be flip at all, but why should I care? I guess I don't see what new
functionality I'm getting that I don't, essentially, already have. Sorry
to be so stupid, but I don't see what I'm missing here . . . .

Thanks,
