The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

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
Also
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?
