The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
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.

Subject: Coding procedures in CL
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?
