Pgorthi,

Reference modification exists in easytrieve but it works using substrings. check out this example.

Code:


DEFINE WS-MESG W 50 A
DEFINE WS-BYTE WS-MESG 1 A OCCURS 50

DEFINE WS-RESULT W 10 A


JOB INPUT NULL

   WS-MESG = 'KOLUSU@MVSFORUMS.COM'

   MOVE WS-BYTE(8) 10 TO WS-RESULT

   DISPLAY WS-RESULT

   STOP



WS-RESULT will now have MVSFORUMS.

Hope this helps...

Cheers

Kolusu

pgorthi,

If your input file is huge then the above code will take some time to complete.

Check the following link for a more optimized solution (by none other than Kolusu) - It uses Index in the OCCURS class. It has been proved it could reduce the run time by more than 50%.
