Re: CL command creation

I would like to build a command to return sysName and libName.

But, I would like the variables to be optional when using the
command.

Examples:

Command name is GetEnvr

I would like the following to be functional:

GetEnvr (&sysname) (&libname)

GetEnvr () (&libname)

It appears that if I want to return a value, then the value MUST be
used in every call of the command. Is it possible to make a return
variable optional?
