 Posted: Thu Jan 13, 2005 12:06 am Post subject: PASSING DATA > 32 K |
 |
|
Hi,
I have this CICS COBOL program that LINKS to a program BY REFERENCE. I want to send and receive data from the Calling program. The called program currently receives the data in the DFHCOMMAREA and has a storage as
01 DFHCOMMAREA.
05 WS-PASS-TEXT PIC X(32765).
05 WS-PASS-LEN PIC S9(04) COMP.
The subprogram does some parse logic and passes data and length back the called program.
Is there a way to pass data > 32K in COMMAREA? I know this can be done another way by passing the ADDRESS of WS-PASS-TEXT (CALL BY CONTENT) to the DFHCOMMAREA; can anyone give a simple example to do this?
Thanks
Gary |

Gary_fsee,
Here is an example of passing 40k to subprogram.
Main pgm:
| Code: |
WORKING-STORAGE SECTION.
01 WS-DATA.
05 WS-COMMAREA-REC.
10 WS-COMMAREA-LGTH PIC S9(09) BINARY.
10 WS-COMMAREA PIC X(40960).
05 WS-POINTER POINTER.
MOVE SPACES TO WS-COMMAREA-REC
SET WS-POINTER TO ADDRESS OF WS-COMMAREA-REC
MOVE LENGTH OF WS-COMMAREA TO WS-COMMAREA-LGTH
EXEC CICS LINK
PROGRAM ('PASSPGM')
COMMAREA(WS-POINTER)
END-EXEC.
|
PASSPGM
| Code: |
LINKAGE SECTION.
01 DFHCOMMAREA.
05 LS-POINTER POINTER.
01 LS-COMMAREA-REC.
05 LS-COMMAREA-LGTH PIC S9(09) BINARY.
05 LS-COMMAREA PIC X(16777215).
IF EIBCALEN NOT < LENGTH OF DFHCOMMAREA
SET ADDRESS OF LS-COMMAREA-REC TO LS-POINTER
ELSE
PERFORM CICS-RETURN
END-IF.
|
Hope this helps...
Cheers

kolusu,
A follow-up question on this subject. I came across a note that said CICS can have 32K as the upper limit in the Commarea request but can only respond back upto 24K. Basically, 32K is only one way into the system. Is this a valid statement. I came accross this on another board long time ago and not from MVS manuals. Thanks |
