Re: Retain Command Messages

["Steve Landess" <steve_landess@xxxxxxxxxxx>]

Donnie,
If I understand you correctly, you want the message(s) returned by the PING
command -

Example:  "Verifying connection to host system WWW.INTSVCS.COM at address
198.104.188.207"

to persist on the screen AFTER your command has finished.  If this
assumption is correct, after using QCMDEXC to execute the PING command, you
need to (in a loop, until all messages received) receive these messages from
the program message queue using the QMHRCVPM API, then use the QMHSNDPM API
to re-send the received message to the *PRV message queue.  In this way they
"bubble up" to the top of the program call stack, thus causing them to
appear on the screen after the command has finished.

Since these two API's function similarly to the RCVMSG and SNDPGMMSG
commands, here is a simple CL program that illustrates this concept
(sorry-no RPGIV examples handy).  This CL example also handles any other
messages like *ESCAPE or *DIAG messages as long as you have the global
MONMSG command coded correctly.
