Re: MQ Version 9.0 upgrade changing pgm's?

[Charles Wilt <charles.wilt@xxxxxxxxx>]

So what's happened is that IBM removed the old MQ *PGM objects...

To interact with MQ, you'll need to call a bound ILE procedure.

If you've got RPG III (or IV) prgrams using the old-style dynamic calls

C  CALL   QMQM
C  PARM   WHATEVER

Then you've got some work ahead...

If you're using prototyped calls
     DMQCONN           PR                  EXTPGM('MQCONN')
     D* Name of queue manager
     D QMNAME                        48A
     D* Connection handle
     D HCONN                         10I 0
     D* Completion code
     D CMPCOD                        10I 0
     D* Reason code qualifying CMPCOD
     D REASON                        10I 0

         call MQCONN(wQm:handle:code:reason);

Then it might be as easy as changing EXTPGM('MQCONN') to EXTPROC('MQCONN')
note the above PR was actually for EXTPROC, no idea what the EXTPGM version
actually looks like, since IBM removed the copybooks with the at MQ v6.

Judging by the fact that EXTPROC of the PR doesn't take advantage of
procedure functionality, no CONST or VALUE and no returned values.  I
suspect that the params are pretty close to the same between the PGM and
PROC versions.

Also to re-iterate, IBM removed the older copybooks (with EXTPGM PR's?) at
v6 of MQ.  Assuming you are running a version newer than that and you've
compiled your program since, either you've got your own version of the
copybooks or you're already using the bound interface and would be fine
upgrading to MQ v9.

Depends on rather or not IBM changed they parameters...I can't
