Re: Difference between CPF0000 and CPF9999

Hello, Kaylan:

First, you can monitor for a specific message, e.g.:
    MONMSG    MSGID(CPF9801)

Or you can monitor for a list of specific messages, e.g.:
    MONMSG    MSGID(CPF9801 CPF9802 CPF9810)

Next, you can monitor for a whole group of related messages, using a
"generic" designation such as:
    MONMSG    MSGID(CPF9800)

-- this will trap any message that begins with CPF98xx.

Next, you can monitor for a truly generic message, such as:
    MONMSG    MSGID(CPF0000)

-- this will trap any message that begins with CPFxxxx.
-- typically this is used in a "global message monitor" statement at the
start of the program, e.g.:
    MONMSG    MSGID(CPF0000 MCH0000) EXEC(GOTO ERROR)

For these message IDs to be considered a "generic pattern" it must end in
"00" or "0000".

Finally, it is my understanding that, if a CPF message occurs and is not
"handled" in the CL program, in other words, there was no active MONMSG that
matched the message ID either exactly or as a generic pattern, then it is
converted into a CPF9999 and that exception is raised ... so you can also
monitor for CPF9999. But, due to this extra processing that occurs before it
is converted to CPF9999, you may get additional messages, such as the one
that tells you there was an unhandled exception and asks if you want a
"dump" etc.

At least, that's my understanding or interpretation of "how it all works"
...

Hope that helps ... ;-)
