Anytime I am passing parameters for returning data, as opposed to returning a result set, I set them both as INOUT.

Subject: Calling a stored procedure from RPG
Does anyone know how to call a SQL Stored procedure from RPG and pass in integer and receive the response back in the output variable?
We are having an issue where the input parameter doesn't appear to be mapped to the input parameter (RTID), and the CREDSTRING output variable is always blank.
We are able to successfully call the procedure using straight SQL. It just doesn't work from RPG.
Here is the SQL Stored procedure def:
CREATE PROCEDURE TESTLIB.GETCREDSTRING (
IN RTID INTEGER ,
OUT CREDSTRING VARCHAR(50) )
MODIFIES SQL DATA
CALLED ON NULL INPUT
SET OPTION ALWBLK = *ALLREAD ,
ALWCPYDTA = *OPTIMIZE ,
COMMIT = *NONE ,
DECRESULT = (31, 31, 00) ,
DFTRDBCOL = TESTLIB,
DYNDFTCOL = *NO ,
DYNUSRPRF = *USER ,
SRTSEQ = *HEX
One input parameter RTID (integer), and one output parameter (credstring)
Our RPG program is as follows:
CTL-OPT DATFMT(*USA) DEBUG(*YES) DFTACTGRP(*NO) ALWNULL(*USRCTL);
DCL-S InParm int(10);
DCL-S OutParm VARCHAR(50);
InParm = 0000600002;
call getcrdsp (:Inparm, :Outparm);
*INLR = *ON;
