Checking for Optional Parameters in CLLE

Now that we have %ADDR and the *NULL keyword in CL/ILE, it would be awfully, awfully nice (for cross-language consistency) that since we have %PARMS, %PARMNUM, and the *BLANKS and *ZEROS keywords in RPG/ILE, that we could also have the same in CL/ILE.

There are a couple of other RFE's in this area (one even from me):

However, they don't go far enough for the full functionality I am requesting with this latest RFE.

Use Case:

I can check for optional parameters as follows in RPG/ILE:

if %parms() < %parmnum(OptRun) // if parm not passed
or %addr(OptRun) = *null // or parm was omitted
or OptRun <= *blanks; // or parm is blank
else; // keep default, else
RunOpt = OptRun; // replace default

I should be able to do exactly the same in CL/ILE -- as follows:

    Support of *BLANKS and *ZEROS are under consideration but with low priority, since 103104: Add new function *BLANKS and *ZEROS on CLP is already for the rest part, close this one with delivered.

    The new %PARMS built-in function for ILE CL compiler by PTF SI66721 for V7R3.
    %PARMS returns the number of parameters that were passed to the program in which %PARMS is used.
    Support of *BLANKS and *ZEROS are under consideration.
