Re: %EOF

["Scott P. Johnson" <sjohnson@xxxxxxxxxxxxx>]

For "IF EOF LEAVE" it works if you use DOU, but if you use the DOW,
Primer read, and the read at the end, the loop handles the EOF, not 
some extra IF.  Also, sometime back I read an article where they 
compared the DOU and DOW for I/O.  They decided the DOW was a much 
better way to do it. Clean Cut, No extra IF, and so on.

As for ITER it is just a GOTO in disgiss, same with LEAVE.  Some
people just don't use GOTOs, I am one of those people.  I think code
is a lot more maintainable not using them.
