I am getting ASRA abend when calling a simple assembler program from cics program. I am just trying to pass a 12 byte data from cics to assembler and receive a success return code. Please help me to resolve the issue. Thanks.

CICS program :


Code:
       LINKAGE SECTION.                                               
       01 DFHCOMMAREA PIC X(12).
     
       CALL 'PACASM01'  USING WS-DATA



Assembler program :

Your CALL parameters must be DFHEIBLK DFHCOMMAREA WS-DATA.

Establishing addressability to WS-DATA will be 8-Off Register 1. This register will contain a 12-Byte parmlist address and the address for WS-DATA can be found as the last word.

It looks like you've Assembled the program as CICS/Assembler because you've used DFHEIENT.

Don't worry about the RSA as saving and restoring registers will be automatically performed by the program.

When returning to the Caller, use -

Code:

DFHEIRET RCREG=R15

Which will pass back the return code (R15) and is addressable in COBOL as the RETURN-CODE Special-Register.

Instead of a WTO (which is an MVS SVC 35) take a look at the CICS method of write to the operator via the "WRITE OPERATOR" API.

However, instead of this API, you can write a message to one of the external TDQ's, such as CSMT, CSSL, etc. Check with your CICS System Programmer as to which one to use.

One last recommendation, ensure that the sub-program is LINKED as AMODE 31/RMODE ANY, because if it's defaulting to AMODE 24/RMODE 24, you're going to get addressability errors, because normally, CICS COBOL programs are LINKED as AMODE 31/RMODE ANY. You do NOT need AC=1 in your Link Edit step. This is where the AMODE and RMODE need to be specified.

Also, the first source line needs to be -

Code:

*ASM XOPTS(SP,NOEPILOG)

Which allows System Programmer API's and suppresses the Program Epilogue, which is what you want to do when using DFHEIRET.

HTH....

I tried below assembler code with AMODE 31 and RMODE ANY. Still getting ASRA abend. It is getting abended while returning.

I realise you are new to this, so give this a try. Ensure when you call this sub-program you call it as -
Code:

CALL WS-PACASM01 USING DFHEIBLK DFHCOMMAREA WS-MSG

WS-MSG will contain a 12-Byte message and WS-PACASM01 will contain "PACASM01". As you can see, 8(,R1) is loaded into R7 and now you've addressed WS-MSG. You were loading R3 with 8(,R1) but the problem with that was R3 was designated as your program (CSECT) base-register. icon_eek.gif

Why are you not using a LINK and just passing the WS-Data commarea instead of a call.

Code:
 
         DFHREGS
         EJECT
WSCLIMSG DFHEIENT CODEREG=(R11),EIBREG=(R12),DATAREG=(R13)
         SPACE 1
         PRINT NOGEN
         SPACE 1
WSCLIMSG CSECT
WSCLIMSG AMODE 31
WSCLIMSG RMODE ANY
IMSGINIT EQU   *
         LA    R2,IMSGSTRG               ADDRESS OF IMSG STORAGE
         LR    R4,R2                           ADDRESS OF IMSG STORAGE
         L     R3,=A(IMSGLGTH)          LENGTH OF IMSG STORAGE
         SR    R5,R5                           IMSG STORAGE LOW VALUE
         MVCL  R2,R4                        CLEAR OUT IMSG STORAGE
         SPACE 1
         LH    R5,EIBCALEN                LOAD THE COMMAREA LENGTH
         CH    R5,=H'0'                      DO WE HAVE A COMMAREA ?
         BE    NCOMABND                  NO - GO ISSUE THE ABEND
         CL    R5,=A(COMALGTH)       IS LENGTH WITHIN BOUNDS
         BH    ICOMABND                   NO - GO ISSUE THE ABEND
         SPACE 1
         L     R9,DFHEICAP                 LOAD ADDRESS OF COMAREA
         USING COMMAREA,R9           ESTABLISH ADDRESSABILITY
         SPACE 1

         SPACE 1
IMSGEXIT EQU   *
         L     R15,RTRNCODE             PASS BACK THE RETURN CODE
         SPACE 1
         DFHEIRET RCREG=(R15)
         EJECT
         LTORG

Hi Mickey,

The original post indicated the OP wanted to use a CALL. As far as using a LINK-API instead, your guess is as good as mine. icon_confused.gif

Mickeydusaor..Thanks for your code.I will use it if i want to link the program instead of a call.

Glad to be able to help with the CALL solution. Mickey's LINK-API solution should also be tucked away for a rainy day. icon_wink.gif

With both solutions, you now have templates with which you can build on.

I am able to send/receive data from assembler when calling from CICS. Now am trying to access dataspace from assembler module. I am able to achieve this in Batch. But when i try from CICS, the CICS region goes down.

Note :

In batch, I created the dataspace and accessed through assembler.In CICS, I am trying to access the dataspace created in Batch through assembler.

CICS/Assembler to access dataspace :

I'm facing this problem either, but I don't acctually know why.
I use a static call to invoke a assembler program from a cobol program under cics, as you know, ASRA occurs.

Thank you.
