Calling an ILE Procedure from CLLE


I have an RPGLE procedure that I need to call from a CLLE program. The issue is the length (and type) of the parameters in the RPG procedure - they are all VARCHAR and range in size from 50 to 1024.

For now, I have it "working" by defining the CL variables as the "maximum size".

For example:
The first parameter of the RPG procedure is VARCHAR(1024), so I defined the CL variable &PARM1 as TYPE(*CHAR) LEN(1024).

CHGVAR VAR(&PARM1) VALUE('about this much data')
CALLPRC PRC('my_rpgProc') PARM((&PARM1) (&PARM2)...)

This seems to work (for now)... but I have this little voice in my head telling me it could be a problem down the road.

I despise CL for this very reason.
