Listers, The doc for the SLIP command's MSGID= operand includes this text describing the register contents when a SLIP trap that uses MSGID= is invoked:
Register 2 - contains the address of the SLIP message data area, found in mapping macro IHASLMSG. I can't find the IHASLMSG mapping macro anywhere on our z/OS V2R4 system. I have searched all SYS1 data sets. Does anyone know where that macro lives?
