If the following RexxRoutine is defined:

    RexxRoutine2(RexxObjectPtr, BsfRexxProxy, RexxObjectPtr, proxy, 
OPTIONAL_CSTRING, arg2val)
      

Is it possible that with the above RexxRoutine2 signature the first
argument 'proxy' can take on the value NULLOBJECT/NULL ? (That value
AFAIK would indicate that an optional argument was missing.)

As the first argument 'proxy' is intended to be mandatory (hence not
using "OPTIONAL_RexxObjectPtr"), it should never have a value of
NULLOBJECT/NULL, correct? (The runtime would raise an error in such a
case, rather than using NULLOBJECT/NULL as its value?)
