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

He should check for the *in03 after the exfmt and not at the top of the
loop.  The loop would better be expressed as DOW 0=0, and then exit
(leave) on *in03.  The way it is if he uses the f3 key the logic
continues to the bottom of the loop and then to the top where it exits.

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?
