No you don't need to retrieve all the values. All you need do is after the
line of code in I assume your CL program that changes the input parameter
to the required value, just MONMSG MCH3601. We have exactly the same
requirement in one of our commands, and do exactly the same thing.

        Subject:        RTV???? command question


I've written a bazillion (it seems like) commands over the years, but
evidently I've not wanted to do this before.

I wrote the following command to retrieve control file information for
an application be used like this:

RTVOWCNT   IPNAME(&IPNAME)     +
            IPADRS(&IPADRS)     +
            ACSUSR(&ACSUSR)     +
            ACSPWD(&ACSPWD)     +
            HSTUSR(&LAPUSR)     +
            HSTPWD(&LAPPWD)     +
            ACSDLPTH(&ACSDLPTH) +
            ACSULPTH(&ACSULPTH) +
            IFSDLPTH(&IFSDLPTH) +
            IFSULPTH(&IFSULPTH) +
            OWCTLFND(&OWCTLFND)

There are times, however, when I need only 1 piece of information, like
this:

RTVOWCNT   HSTUSR(&LAPUSR)

but I can't use it like that because I get the dreaded 'pointer not set
to location referenced'.  In the CL manual it says:

"If no variable is specified for a RTNVAL(*YES) parameter, a null
pointer is passed to the command processing program"

Am I stuck with having to use all the parms all the time?  Or is there a
way for the CPP to detect and handle the null pointer thingie?

Thanks.
