I have a flat file of LRECL 8000. I have to search for the string 'ABC='. If present, then I have to extract into a new variable starting from 'ABC=' till the first occurence of '/'. I am not worried about the rest of the data.
Please note that the position of 'ABC=' is not fixed and will vary from one record to another. I can use INSPECT to check for the existence of 'ABC=' but how can I put it into a new variable.

Please suggest a solution for this.

Hello,

Once you find the 'ABC=' move the characters one at a time to the "output" area (using reference modification on both the input and the output) until you hit the '/'.

Thanks Dick and Anuj for your replies.

Anuj,
I was thinking in the same line as Dick... I will start reading my input file as a group of 4 bytes and when I hit 'ABC=', then start procedding byte by bte until I hit '/'..

Code:
MOVE WS-TEXT (A:4) TO HOLD-VAR             
IF HOLD-VAR = 'ABC='                       
   PERFORM UNTIL WS-TEXT(A:1) = '/'         
      MOVE WS-TEXT (A:1) TO FINAL-VAR(B:1) 
      ADD +1 TO B A                         
   END-PERFORM                             
   SET RECORD-DONE TO TRUE                 
ELSE                                       
   ADD +1 TO A                             
END-IF.                                     



The above code is working. Thanks Dick and Anuj for your time.
