Nits are important - without them I'd have no wit.

Good point - for me this is primarily a possible performance improver and, as you say, is not always applicable.

I'm tired from chasing COBOL issues all night, so I'm picking nits here, but
with MAINT(*DLY/*REBLD), the access paths are not automatically maintained,
