Re: Parameter passing CL to RPGLE

On a v5r4 system I have a CLLE program with

DCL &RC *CHAR 2
DCL &CALLER *CHAR 10
DCL &PARMS *CHAR 111
CALL PGM(OB0050AN) PARM(&RC &CALLER &PARMS)

And an SQLRPGLE program that has

d OB0050AN pi
d @RETURNCODE 2a
d @CALLER 10a
d ptrPARMS *

d @PARMS e ds extname(OB0050PR) based(ptrPARMS)

When I debug the SQLRPGLE program, I can see the values passed for
@RETURNCODE and @CALLER, but for ptrPARMS it shows SPP:*NULL.

Hmm. I would think there would also be a MCH3601 exposed, somehow, to reveal\indicate why the value is presented as *NULL; what does EVAL ptrPARMS:X show?

What am I missing?

The interface does not match to the CALL. The CL would either need to pass the address of (&PARMS) [i.e. CHGVAR (&cl_ptrPARMS) (%addr(&PARMS)) and then CALL … PARM(&RC &CALLER &cl_ptrPARMS)], or the RPG would need to change to type of ptrPARMS to be 111A [and probably best also renamed to something like data_ofPARMS].
