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.

I know that I can call a procedure or subprocedure from CL with
CALLSUBR.
Actually that is the means to call a SubRoutine; the Call Subroutine
(CALLSUBR) CL command\statement invokes the subroutine.
Can I write a subprocedure in CL? One that accepts multiple input
parameters and returns one output parameter? If so, how?
That can be done, at least where the return value is itself a
parameter of the procedure; I am unaware of any support for the CL
/procedure/ to act like a /function/ with a return value [except when
registered and thus invoked as, an SQL FUNCTION]. That can be done by
creating the CLLE module with the command\statement CALLPRC coded to
invoke the [sub] Procedure; more appropriately, that is an external
procedure defined in a separate ILE CL module [source], as there is no
syntax for defining multiple procedures inline to the CL source code.
