WORKING-STORAGE SECTION.

PROCEDURE DIVISION.
PERFORM VARYING X FROM 1 BY 1 UNTIL X<3
DISPLAY X
END-PERFORM
STOP RUN.

IT IS COMPILING WELL BUT AFTER RUNNING THE LOAD MODULE AND IF I CHECK FOR THE RESULT IN THE SPOOL AREA I COULDNT ABLE TO SEE THE SYSOUT THERE( I HAVE GIVEN THE SYSOUT IN THE JCL). PLEASE HELP ME TO SOLVE THE ISSUE.

Hi There,
U would not be able to see any value since it wont enter in the loop since u made the condition until X<3 So as soon as value of X will be less than 3 it will come out from the loop since syntactically its correct but not logically that s why u r not getting any compiler error . To see the value of X please change the code as below
| Code: |
PERFORM VARYING X FROM 1 BY 1 UNTIL X>3
DISPLAY X
END-PERFORM |

Exactly what you found, nothing. The condition was satisfied at the first test and since that test defaults to before, nothing within the perform executed.
Do yourself and the rest of us a favor and learn how to use the "Caps Lock" key on your keyboard (I know you read the forum rules.....). |

I might as well add something constructive (somewhat) to the subject:
If you added "WITH TEST AFTER" to your stmt, the pgm would enter the PERFORM loop once and display the subscript. |
