RTV???? command question

[Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>]

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.
