I don't know about the upgrade question asked later, but I didn't see an
answer to yours so here goes.  Get training if you can, if not, read the
manuals.  The manuals are well-written (compared to others) and fairly self-
explanatory.  MQ is written to process transactions, so don't try to use it
for data transfers of large numbers of records (thousands) in lieu of SNADS.
We wrote a "shell" program to handle MQ processing over two years ago, so I
cannot comment  to the specific technical issues of using it.  MQ (message
queue) Series was written to send messages however, despite message queue
support on the AS/400, it _emulates_ message queues on the /400 with user
spaces so you have a 16Mb limit on how many messages can be queued at one
time.

When we went live, the DEC version of MQ was still running the version from
the third party that wrote it before IBM took it over, while the mainframe and
AS/400 were running IBM versions.  The DEC people had problems at that time
because all of the MQ example code for the DEC was written in C, and they only
had a COBOL compiler for the DEC (ain't UNIX "OPEN"?).

MQ is simple to use.  Open the queue.  GET from and/or PUT to the queue.
Close the queue.  Multiple queues in the same program can be tricky, but
saving the queue name and HCONN value received on the open of each one makes
the usage easy.  The only problem is that the ubiquitous "Run-time parameter"
prevents you from writing driver programs entirely in AS/Set.
