RE: Coding procedures in CL

Hi Rob
Are you talking about procedures/subprocedures or subroutines?

Rob,

At V5R4 in CL you use the CALLSUBR command. You can have a value returned from the subroutine/subprocedure but you cannot pass parameters to it. Variables are all defined globally. You cannot define variables within the subroutine/subprocedure.

You can have 256 subroutines. I tend to place them at the end of the program.

DCL my stuff
Run the commands
o Any errors go to error handling.
o No errors then return
Error handling
o Handle error
o Return
Subroutines.

Each subroutine starts with SUBR SUBR(yourname) and ends with ENDSUBR. You can exit the subroutine with RTNSUBR RTNVAL(yourvalue).

HTH.

Gary

I know that I can call a procedure or subprocedure from CL with CALLSUBR.
Can I write a subprocedure in CL? One that accepts multiple input parameters and returns one output parameter? If so, how?
