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

I am sorry but it doesnt matter whether it is a DOW or DOU the logic of the 
program MUST go from the screen and through the steps to the end of the loop, 
so it will ALWAYS write a record to that file no matter what you do.

Or am I missing something?

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

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?
