    CL message handling

    Hi,
    I have a menu option that calls a CL that calls several other CL's which all have the possibility of failing during processing. Each program has message handling built in but how do I get a message generated in program C, that was called from program B, that was called from program A, to display to the user running the menu option to inform he/her that a program failed somewhere downstream?

    You can make each program resend the error it receives to the caller. IBM i has two good API's for this: QMHMOVPM and QMHRSNEM. I use Brian Rusch's command interfaces to these API's in my CL programs.

    You can find more information here:

    Note: The code accompanying this article is available for download here. I had the great pleasure of meeting Brian Rusch in Milwaukee last month, when I spoke to the Wisconsin Midrange Computer Professionals Association (WMCPA). Brian told me about the method his shop uses to handle CL program exceptions. I’d like to share it with
