Re: Overlay an External DS

I hear rumors that this gap will be tightened up as time goes on.

Yeah, I notice that some of the mails are coming out of order (and
slow).

BTW, your solution *did* work, I had a non-related error in my program,
but fixing that didn't help the overlay situation.  Do I understand that
this might be caused because we have 2 compiler teams?  If so, then I'm
not so comfortable using SQLRPGLE, which is a shame cause I really like
it (usually).

Thanks!
