You could check if the address of the parameter is NULL - then the parameter
was not passed.

Like this

IF %ADDR([variable_name] = *NULL;
.... do something or whatever...
ENDIF;

I have found this particularily useful when using RPG programs as CPP for
commands that return values since you really do not know which values are
requested.
