Could anybody let me know as to what compiler options should I be using to make a COBOL Program Re-entrant...

So if I have a cobol program calling other programs, can I keep the working storage of the called program resident in memory, if I make it re-entrant ?

Do I need to use run time options like HEAP, other than the compiler options RENT, RMODE & DATA to make this happen?

A reentrant program, while being executed in the common virtual area so that once copy of it amy be shared among all callers. i thnk u can use RENT compiler option.

RENT is required for CICS programs. RENT causes the compiler to produce rentrant code and allow u to place cobol modules in the LPA or ELPA and thus shared among multiple address space under CICS. These modules cannot be overwritten, since LPAand ELPA are read-only storage.
note: LPA indicates link pack area.

i just gave a trail. pls correct me if i am wrong.
