An ILE RPG “program” cannot have parameters passed by VALUE.

And a parameter passed as CONST does not need to be passed as a ‘constant’; even CL can call a program with a CONST parameter. The CONST attribute is technically more for the compiler than the developer. The prototype in the calling program does not have to specify CONST, so OPM RPG has no problem.

Martin’s right. We need to know what the error is and what the calling code looks like. It should look like the code for any other CALL.

If so, you have to create a wrapper ILE program, receiving parameters in the way RPG III can handle (by reference) and forwarding them to original RPGLE program. The parameter by reference is the default mode, they do not have any special keyword, the read only by reference has the CONST keywoerd wich mean it can not be changed in the called program.
