I'm having a hard time finding an answer to this..

Let's say PGMA reads in data area DTAARA1 with *LOCK, updates the data area
value , then uses OUT to update the data area (and unlock it).

PGMB also does the same thing. Let's say they happen to run at the same
time (but PGMA got there first)... how long does PGMB wait until it issues
an error saying it can't lock the data area?

The update is very quick.. it's really just incrementing a counter value
stored in the data area and returning the value.

Are you seeing a hang? Getting a message?

Aside from DFTWAIT() I dimly recall an internal (system) lock when the
'write' actually occurs but I can't recall the error message that ensues
if it gets tripped.
