RE: Variable length variables and data queues

My understanding is that the CRTDTAQ MAXLEN parameter sets the entry length,
not the number of bytes allocated for the queue. If MAXLEN = 100, each entry
on the queue can be a maximum of 100 bytes.

The size of the queue - is it the maximum per entry or the maximum of the
sum of all entries on the queue?  To keep a queue from filling quickly, I
have always made the maximum queue size large so I thought the latter was
true.
