Yes, if your caller passes *OMIT, your procedure gets a null pointer.

Rule of thumb:
- If you use OPTIONS(*NOPASS), you have to use %PARMS to see if the
parameter was passed.
- If you use OPTIONS(*OMIT), you can check for a null pointer.
- If you use OPTIONS(*NOPASS : *OMIT), you have to first check %PARMS
and then you can check for a null pointer.
