Hi Kolusu,

Today only I found the answer. If I knew the answer already I would have posted it in Mainframe Challenge.


Thanks for your support.

Code:

       IDENTIFICATION DIVISION.                                         
       PROGRAM-ID.                       COB1.                         
       AUTHOR.                           DTF.                           
       ENVIRONMENT DIVISION.                                           
       CONFIGURATION SECTION.                                           
       SOURCE-COMPUTER.  IBM-390.                                       
       OBJECT-COMPUTER.  IBM-390.                                       
       DATA DIVISION.                                                   
       WORKING-STORAGE SECTION.                                         
       01  TEST-FIELDS.                                                 
           05  ODD                    PIC 9(4) VALUE 123.               
           05  EVEN                   PIC 9(4) VALUE 124.               
       PROCEDURE DIVISION.                                             
           IF ((ODD / 2) * 2) = ODD                                     
              DISPLAY 'ODD TEST FAILED'                                 
           ELSE                                                         
              DISPLAY 'ODD TEST WORKED' 
           END-IF                               
           IF ((EVEN / 2) * 2) = EVEN                     
              DISPLAY 'EVEN TEST WORKED'                 
           ELSE                                           
              DISPLAY 'EVEN TEST FAILED'
           END-IF
               
           GOBACK.                                       


This seems to work and displays:
ODD TEST WORKED
EVEN TEST WORKED

dtf,

The trick here is NOT to use any conditional Statements.
