You should be able to set values in a C program as long as CL program passes
in the variable.  You simply need to dereference the argv parameter and set
it, i.e.:

*argv[3] = rrn;

My Bad.  The way I showed you was if you were calling an exported
procedure.  (From a *MODULE or *SRVPGM)  I rarely CALL a program
anymore.

- = - = - = - = - 

When creating a new CL, use CLLE for your Source Type.  You may have to
compile your CL as a *MODULE (use opt 15) and then use CRTPGM to create
the final program.  

Define the two variables as below, and use the CALLPRC command instead
of the CALL command to run your C code.  (You can prompt it if needed.)

The odd thing is you have to use the %BIN function twice.  When used in
the RTNVAL option, it tells the compiler that you will be getting back
an integer.  Since CL has no INT type, it is stored as a 4 byte
character field.  (Hence the defintion of &wrkINT as *CHAR 4)  The
CHGVAR use of %BIN actually changes the value to a packed format. 

DCL VAR(&wrkINT    ) TYPE(*CHAR) LEN(     4)
DCL VAR(&RRN       ) TYPE(*DEC ) LEN(  15 0)

CALLPRC PRC(program) PARM(parm1 parm2 . . . parmX)
   RTNVAL(%BIN(&wrkINT))
CHGVAR  VAR(&RRN) VALUE(%BIN(&wrkINT)) 

- = - = - = - = -

RTVJOBATR can give you a return code from a CALLed program, but the help
says just COBOL, RPG, DFU and sorts.  I've never used it.

Do you have or do you know where I can find an example of this approach?
I'm not familiar with CLLE,so if I could see a sample, I could clone
it...
