Just wondering, for comparing several subfields individually, which is what I think this would be, what defines less or greater? I can see some subfields less than, others greater than.

Yes - I really do think, that the idea of a "comparator function" makes sense for that case.

There's an Idea about providing a comparator function for %LOOKUP and SORTA. https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-1461
"Possibility to specify a compare procedure for SORTA and %LOOKUPxx"

The comparator function could also be used for some new %COMPDS built-in function.
