Here is how to use search option in COBOL

COBOL Declaration:

01  A1-TABLE.                                               

    03   FILLER                     PIC 9(02) VALUE  01.    

    03   FILLER                     PIC 9(02) VALUE  02.    

    03   FILLER                     PIC 9(02) VALUE  03.    

    03   FILLER                     PIC 9(02) VALUE  40.    

    03   FILLER                     PIC 9(02) VALUE  50.    

                                                               

01 AE-TABLE REDEFINES A1-TABLE.                            

    03  IE-CODE        PIC 9(02)  OCCURS 5 TIMES           

                           INDEXED BY P1.                     

Code in procedure division : 

      SET P1 TO 1.                                

      SEARCH IE-CODE                            

          AT END SET NOT-IE-CODE TO TRUE        

      WHEN AE-CODE IS EQUAL TO IE-CODE (P1)   

          SET IE-CODE1 TO TRUE
