External Subroutines

Hi,

I want the difference between External and Internal subroutines.
How is external subroutine different from a program?

Visvanathan,

I can find no direct reference to 'EXTERNAL' or 'INTERNAL' SUBROUTINES, but what I think you are referring to by 'EXTERNAL' is a separately compiled program, and by 'INTERNAL' is a nested program compiled within another. See the link below.

If this does not answer your question, please come back.

These two terms are used in SAG Natural. INTERNAL is a subroutine coded within the executing program/subprogam with a DEFINE SUBROUTINE.. END SUBROUTINE command verb.

A subroutine created as an element in Natural is the EXTERNAL Subroutine.

Okie..Thanks a lot.

1 more query. How is Static and Dynamic call differ?

2 How will I pass a value from JCL to a Source? I need the syntax for both the cases.
