RE: Data Structure Array Lookups

["Coyle, Stephen F." <SCoyle@xxxxxxxxxxxxx>]

I ended up creating 2 arrays like you suggested. I thought I could get
it to work the way I had it but I've got to move on. 

Thanks Alan and Joe...

I haven't tried it, Steve, but I don't think it will work the way you
want.
Every example I've seen of this type of thing uses OVERLAY(*NEXT) and a
DIM
on each subfield.  I think you might have to put an extra field in your
data
structure that is defined like I1$ITT, and then remember to populate
that
field when you populate the record.  Then you can sort or lookup on that
field.

But if you're not sorting, you're making a lot of extra work for
yourself.
Just create two arrays, one with the data and one with the keys.  Do the
lookup on the key array and use the index for the data array!
