1. Exported Procedures should not be in the same member as a linear or cyclic main procedure.
2. Exported Procedures should be bound into a Service Program
3. The service program should be bound to the program.
The easiest way is to register the Service Program in a Binding Directory and then specifying the binding directory in the compile command or even better register in the H-Specs/CTL-OPT keyword BINDDIR

Subject: EXPORTing subprocedures
OK, here is something I have never quite understood. Can anyone explain why subprocedures within a Linear Main *MODULE have to be EXPORTed - even when only referenced within the same *MODULE?
Example: A single source member follows, (please be gentle with my
coding.) CRTBNDRPG used with this particular example.
**Free
// Linear Main *MODULE with subprocedure // Subprocedure MSG requires EXPORT keyword - why???
Ctl-Opt DftActGrp(*No) Main(MainProc);
Dcl-PR MainProc ExtPgm('PGM2_PROC1');
End-PR;
Dcl-Proc MainProc;
Dcl-PI MainProc;
End-PI;
Dcl-PR Msg;
End-PR;
Dcl-S UserId Char(10) Inz(*USER);
Dsply 'In MainProc' UserId;
Msg();
Return;
End-Proc;
Dcl-Proc Msg Export;
Dcl-PI Msg;
End-PI;
Dcl-S UserId Char(10) Inz(*USER);
Dsply 'In Msg Proc' UserId;
Return;
End-Proc;
If I rewrite the above as a Cycle Main *MODULE, the EXPORT keyword is not required on the subprocedure. The RPG Reference states:
"If the EXPORT keyword is not specified, the procedure can only be called from within the module."
So why is EXPORT needed in the above example? (If it is removed, a bind error occurs.)
Thx for any insight.
Brian.
