Re: UDF return *PGM parm?

Yes - that shouldn't be a big problem.

You have to use

PARAMETER STYLE DB2SQL

in the function definition. AFAIK "SQL" does also work, but I always use "DB2SQL".

With this you will have a parameter the contains the return value for the function.

Still one of the best resources for UDFs and UDTFs is Scott's presentation:
https://www.scottklement.com/presentations/RPG%20User%20Defined%20Functions%20&%20Table%20Functions.pdf

Scott's example is with a *SRVPGM procedure, but it works the same with a *PGM - it differs only in the EXTERNAL NAME clause.

I'd wager this is a long shot, but it can't hurt to ask.

I have an RPGLE *PGM that has a parameter that's basically an output
parameter. Is there a way to create an SQL UDF that can use that *PGM
object and make that output parameter an actual return value?

*SRVPGM is off the table. Don't ask... :(
