Can someone please help in finding out the position where the phrase is encountered in the text.

for examle : Mainframe Forum is very useful for programming.

Here i need to know the position where the word programming is appeared. This word can occur at different position dynamically based on the input text.

Hi, you can try this:
Code:

01 MATCH-STATUS   PIC X(1) VALUE 'N'.
   88 NO-MATCH             VALUE 'N'.
   88 MATCH-FOUND          VALUE 'Y'.

PERFORM UNTIL Z = LENGTH OF A OR MATCH-FOUND   
COMPUTE Z = Z + 1                             
IF A(Z:11) = 'PROGRAMMING'                           
SET MATCH-FOUND  TO TRUE                       
MOVE Z TO K                                 
END-IF                                         
END-PERFORM                                   
DISPLAY " VALUE OF K :" K

Hope this helps

Cris

Thanks Chris..

Do you have any idea of the below ?

Is there any way we can do the same logic with INSPECT or STRING / UNSTRING command.. I'm trying out with UNSTRING WITH POINTER but it seems doesnt working.

bamohan,

If you want to know the position of initial occurrence of a string, you can try this.
Code:
----+----1----+----2----+----3----+----4----+--
MAINFRAME FORUM IS VERY USEFUL FOR PROGRAMMING.

Code:
     05  I                               PIC  9(02)       
                       VALUE   0.                         
     05  STRING-1                        PIC  X(80)       
                       VALUE                               
         'MAINFRAME FORUM IS VERY USEFUL FOR PROGRAMMING.'.
                                                           
***********************************************************
 PROCEDURE DIVISION.                                       
***********************************************************
                                                           
 0000-MAIN-PARA.                                           
          INSPECT STRING-1 TALLYING I FOR CHARACTERS       
                  BEFORE INITIAL 'PROGRAMMING'             
          COMPUTE I = I + 1                               
          DISPLAY 'I :' I       

SYSOUT
Code:
