I discovered why the 62 error code was occurring.

I was doing a DBLOCK mode5 inside the loop. Not good, luckily I
didn't get a system deadlock. That didn't happen because the item
being locked had a different value with each record being read from
BASE-1. So, if Base-1 had 1,000 entries I was doing 1,000 DBLOCK
mode5. Ouch, not good.

I took the DBLOCK mode5 out of the loop and placed it with the
DBLOCK mode3 on BASE-1. Not exactly how I wanted to do it but
it works. No more 62 error code.....

Thanks to everyone who responded.

Brian.
