David, Doubtless you'll have coded this by now, but certainly in the situation you describe, I'd store just the 'as typed' case version of the list on disk, then immediately after read, I'd create an in memory 'all uppercase' version in one go - just UPCASE the whole attribute - and I'd probably RAISE it to because I like working with multi-attributed lists in preference to multi-valued. Then, for each insert into the list I'd LOCATE BY 'AL' the UPCASEd version of my new name in my UPCASEd complete list, SETTING an attribute index position and then INS before the relevant attribute in my UPCASEd list and before the relevant value in my 'as typed' array.
The CPU overhead of UPCASEing the whole name list should not be much because it is a single pass through a string applying a simple transformation with no growth or shrinkage involved. The risks involved in maintaining 2 parallel lists on disk along with the messiness of that solution would be enough to rule that option out for me.
