Re: while exit from the dsply fiel its adding a blank record with 0'

The DOU loop checks at the end, so it is always executed at least once.

Shiva -
I'm NOT going to give you the technical answer, but anyone who has had the CS101 course (basic programming logic) has surely been taught that a DO WHILE loop (RPG/400's DOW operation) doesn't check the looping condition until it reaches the END of the loop (RPG/400's ENDDO operation). 

I think that's incorrect.  Doesn't the DOW check at the start of the loop
and the DOU check at the end?
