Hi All

I need to CALL a non-cics program from my CICS programs.

PROG A ----CALL -----PROG B

ProgA is in lib PDS1 in the cics region and ProgB is in PDS2. So do i need to add PDS2 ib in my region concatination for calling PROGB

Yes, you would have to add the library where the program resides to the CICS/DFHSIP load lib concatenation.

You have two choices to access this sub-program -

01) CICS (not an MVS) Dynamic CALL (explicit PPT entry or autoinstalled model)

02) Static CALL (PPT entry not required)

I'd go for the first one.

Calling a sub-program Statically can cause some real headscratching.

With that, it is highly recommended that Statically called sub-programs are passed reentrant WORKING-STORAGE from the CICS caller.

Otherwise, you may have some "opportunities" to deal with in the future, having introduced non-reentrant access to CICS.

If i do a static call i don't need the library need to be addded in the regiion rite?
