Re: Parameter passing CL to RPGLE

Because it's passed by reference. My understanding (apparently incorrect) is that when passed by reference, a pointer is passed to the called program.

When you talk about how the 111th byte is set, are you referring to how 1-byte indicators are passed?

As you are passing &PARMS as a character string, why would you expect it to
show up as a pointer in OB0050AN? And just changing the third parameter of
the RPG program to 111a may or may not work as expected based on how the
111th byte is set in the CLLE program.

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.

What am I missing?
