Maybe I'm missing it, but I don't see where the RmvMsg subprocedure is called.

Subject: QMHSNDPM, QMHRMVPM, & Error Message Subfiles
To begin, I've looked through the archives and have not found a solution to
the problem I'm having. Secondly, this is my 1st attempt at using error
message subfiles (in RPG) and the two APIs. I coded the two APIs in
subprocedure calls in the main program. I'll eventually incorporate them
into a service program, but I wanted to keep it simple to begin with.
The user is presented with a subfile (in a window) where they enter check
numbers, which are then validated. A single check number can generate
numerous errors, hence the perfect "excuse" to use an error message subfile.
Field PgmPgmQ (in the DDS) is set to the PEP procedure name. The sending
and displaying of the messages work perfectly - that is only on the first
pass. Using QMHRMVPM to clear the queue (prior to re-validating the input
on subsequent passes) does not appear to be working. Checking the error API
data structure in debug mode reveals nothing at all. So, each time the
check numbers get validated, the error messages pile up in the subfile
message queue. Here's some snippets of the code:
The DDS:
A R ERRSFL SFL
A SFLMSGRCD(8)
A MSGKEY SFLMSGKEY
A PGMPGMQ SFLPGMQ(276)
A R ERRCTL SFLCTL(ERRSFL) OVERLAY
A WINDOW(NTRKEY)
A LOCK
A SFLSIZ(50) SFLPAG(1)
A 03 SFLEND
A 03 SFLDSP
A 03 SFLDSPCTL
A 03 SFLINZ
A PGMPGMQ SFLPGMQ(276)
The subprocedures:
P ErrMsg b
D ErrMsg pi
D pChkNbr 7s 0 const
D pErrTxt 256a const options(*varsize)
D SndPgmMsg pr ExtPgm('QMHSNDPM')
D MessageID 7a Const
D QualMsgF 20a Const
D MsgData 256a Const
D MsgDtaLen 10i 0 Const
D MsgType 10a Const
D CallStkEnt 276a Const
D CallStkCnt 10i 0 Const
D MessageKey 4a
D ErrorCode likeds(dsEC)
D wwMsgLen s 10i 0
D wwTheKey s 4a
D errTxt s 256a
C eval errTxt = '#' + %char(pChkNbr) + '- '
C + pErrTxt
C ' ' checkr errTxt wwMsgLen
C callp SndPgmMsg('CPF9897': 'QCPFMSG *LIBL':
C errTxt: wwMsgLen: '*INFO':'*CTLBDY':
C 0: wwTheKey: dsEC)
P e
*---------------------------------------------------------------------
----
P RmvMsg b
D RmvMsg pi
D RmvPgmMsg pr ExtPgm('QMHRMVPM')
D CallStkEnt 276a Const
D CallStkCnt 10i 0 Const
D MessageKey 4a Const
D MsgToRemove 10a Const
D ErrorCode likeds(dsEC)
C callp RmvPgmMsg('*':0:' ':'*ALL':dsEC)
P e
It's probably something trivial...what I need is a really good primer on using
the message handling API's with error message subfiles. Thanks.
