Hi,

In my COBOL program, i have to error out the program by populating Return-Code register with value of '1000',
so that i can trigger a mail in JCL with RC = 1000. to achieve the above condition, it's enough to populate return-code register with '1000'? Please clarify.

Thanks,
Murali

The manual isn't clear enough? See the manuals link at the top of the page.

A "STOP" , or "STOP RUN" afterwards would help.

In as much as COBOL defines this as a "REGISTER" (really a misnomer), the compiler treats it as a signed binary-halfword, which has a maximum signed positive value of +32767.

However, there should not be any problem with a value of +1000.

Hello,

For a bit of entertainment/education, try:
Code:

MOVE 4444 TO RETURN-CODE.
GOBACK.

I used the Below piece of code in Pgm and

Code:

        MOVE '04'             TO RETURN-CODE         
        MOVE 'Data Err in App-def:'                   
                              TO ERROR-ERR-DESC(1:19)
        PERFORM Z1000-DISP-ERR-INFO                   
           THRU Z1000-EXIT                           
        PERFORM Z9999-EXIT-PROGRAM                   
           THRU Z9999-EXIT                           
.
.
 Z9999-EXIT-PROGRAM.     
     STOP RUN.           
 Z9999-EXIT.             
     EXIT.               



In Jcl

Code:

//*EXECUTION OF PROGRAM
//P243CA02   EXEC PGM=IKJEFT1A,TIME=800
.
.
//      IF   P243CA02.RC<4  THEN                                       
//P243BA02   EXEC PGM=IEBGENER,TIME=800

//SYSUDUMP   DD   SYSOUT=*                                             
//      ENDIF       




my JESMSGLG is

Code:


-J243CA1  P243CA02    04    672    779    .00
-J243CA1  P243BA02 FLUSH      0      0    .00
-J243CA1  P243BA03 FLUSH      0      0    .00


Please let me know why after execution of my program, the Job is not picking up my RC.

Thanks,
Murali

Hello,

I still believe something could be learned from this. . . .

Hint: the return code will NOT be 4444. . .

A return code is only allowed in the range of 0 to 4095; this limit is mentioned in the JCL Language Reference several times. If a return code greater than 4095 is set, the system reduces it using modulus arithmetic (4096).

4444 - 4096 = 0348, so the return code set in COBOL at 4444 becomes 0348 as far as JES and z/OS are concerned.

Hi Robert,

Strange but a very good point.

Quote:

If I move 4096 to the RETURN-CODE register then will 0 get moved to the same after using modulus arithmetic?

If yes, we should be very careful as RETURN-CODE zero is fine.

Hello,

Yes, 4096 will cause a return-code zero. . .

Which is why the experiment was suggested. . . . icon_wink.gif

Aaru: when doing batch FTP with the EXIT parameter, this becomes relevant as FTP errors set the return code as a 5-digit number: 2 digits for the FTP command being executed (16 for GET and 27 for PUT, for example) followed by the 3-digit response code from the server. A common code is 16550, which occurs when you attempt to GET a file that isn't there. The 16550 turns into a 0166 return code for the job step due to modulus arithmetic.

Hi Robert,

That was indeed a good information. Will keep this in mind.

Thanks a ton.
