Yes, a data queue can be "full".  If entries are not removed as fast as
they are added, or not removed at all, it will eventually reach it's
size limit and generate an error.

Out shop uses data queues to multithread some of our batch processes.
One job feeds many which actually do the work.  If the jobs taking
entries off of the queue don't keep up with the job placing entries on
the queue it will fill up.  This happens regularly for some of the
processes.  That's why the check.

The question was intended to be what is the best way to handle a
situation where your program goes into an indefinite wait until a
condition is met.   One of the posts from the original thread mentioned
never placing code in production similar to what I gave as an example.
That got me to thinking, if it shouldn't be done this way, then how
should it be done?  No offense taken by the comment, just curious and
always open to better ways of doing things.

The example is not correct code as was pointed out by a couple of the
posts.  I typed it from memory without checking the program.  Really
embarrassing.  I'm looking for the exact code now.

<> 1 is true???

Hi Rick,

DoW 1 = -1
    If data queue is not full
            leave
    EndIf
EndDo

ARe you asking how to tell if a data queue is full?  Or are
you asking how to make an infinite loop?  Or, what are you
asking, exactly?

Is it even possible for a data queue to be "full"?
