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.
Victory goes to those who dare and act and seldom to timid
