Return codes for INMxxxxR exits

INMxxxxR exits are expected to pass back in register 15 one of the following return codes.

Table 1. Standard return codes that all INMxxxxR exits support
Return code (decimal) Description
0 The exit successfully completed. TRANSMIT or RECEIVE processing continues.
12 The exit failed. TRANSMIT or RECEIVE processing ends. RECEIVE issues message IKJ79154I with the reason code in the parameter entry pointed to at offset +24 in the parameter list.

If the exit sets a return code of 12, it also needs to provide the reason code, and might want to set an appropriate action flag in the parameter entry pointed to at offset +40.

16 The exit failed. TRANSMIT or RECEIVE processing ends, and either an exit-provided message or a standard error message is issued.

To have an exit-provided message issued (either message INMX151I for TRANSMIT exits, or INMR151I for RECEIVE exits), the exit must provide the message text in the parameter entry pointed to at offset +44. It must also set the appropriate action flag in the parameter entry at offset +40.
