RE: Ascend on Overlay Subfield

It is sorted by ArAdaEJr and I want to do a %LookUp over KeyEJr. Does

the %LookUp perform a binary search? Or Apply the Ascend key over the
subfields?

%Lookup will do a binary search if the array is in sequence.  By placing the
Ascend keyword on the array you told it that it was indeed in sequence.
Problem is being in sequence on ArAdaEJr doesn't mean that any of the
subfields are in sequence.

Either SORTA on the subfield you want or remove the Ascend keyword or
duplicate the array entry and overlay any subfields you want to lookup
against the non-sequenced version.

It depends on _why_ you want to use lookup on a subfield - it doesn't appear
to make a lot of sense since you can only locate one with that value that
way.
