Hi,

I am in need of some help on GETMAIN, Please do help me

In my program (say PROGRAM1) i used GETMAIN to pass data
In WSS (WM-SEAM-AREA-POINTER POINTER VALUE NULLS. )
In Linkage Section (SEAMCONV-RECORD)

Code:
EXEC CICS GETMAIN
                SET      (WM-SEAM-AREA-POINTER)
                LENGTH   (LENGTH OF SEAMCONV-RECORD)
                INITIMG  (WM-SEAM-AREA-INIT)
                RESP     (CICS-RESPONSE)
           END-EXEC

           IF  CICS-RESPONSE = DFHRESP (NORMAL)
               SET ADDRESS OF SEAMCONV-RECORD
                                       TO WM-SEAM-AREA-POINTER


and Called other program(say WL-PROGRAM2 has program2) using LINK
Code:
EXEC CICS LINK
         PROGRAM  (WL-PROGRAM2)
         COMMAREA (SEAMCONV-RECORD)
         LENGTH   (LENGTH OF SEAMCONV-RECORD)
         RESP     (CICS-RESPONSE)
        SYNCONRETURN
END-EXEC


HOW TO CODE PROGRAM2 TO RECIEVE THE DATA that is transfered using GETMAIN FROM PROGRAM1.

Normal DFHCOMMAREA will do it. Passing data to a CICS program through DFHCOMMAREA doesn't change if you use GETMAIN instead of WORKING-STORAGE.
