posting as a seperate question and not as a response to another similar post this time...
I have been able to get some samples working and am able to substitute character data in the MQMD using a C Message Exit:
| Code: |
| memcpy((PMQMD)((PMQXQH)(AgentBuffer))->MsgDesc.Format , MQFMT_STRING , MQ_FORMAT_LENGTH); |
knowing very little of C, to replace an MQLONG or MQBYTE value properly like resetting the MsgType or Persistance for that matter
what would I need to do to set the MsgType from DATAGRAM to REQUEST:
| Code: |
| memcpy((PMQMD)((PMQXQH)(AgentBuffer))->MsgDesc.MsgType , MQMT_REQUEST , sizeof(MQLONG)); |
does not work as everytime the exit blows up, removing this line everything works... but then the MsgType is not set to REQUEST...
I know I am doing something wrong, so looking for some help...

Michael,
For MQLONG and MQBYTE, just do an assignment.
(PMQMD)((PMQXQH)(AgentBuffer))->MsgDesc.MsgType = MQMT_REQUEST ;
