Actually, you said that backwards...

DOU is tested at the bottom, the loop is always done at least once.
dou 1= 1;
dsply 'HI';
enddo;

Will display HI

DOW is tested at the top, the loop may not be done at all.
dow 1=2;
dsply 'HI';
enddo;

Will not display HI

I has morphed quite a bit.

I personally like the DOU just because the read is at the top rather than
the bottom in general. Truly it does and a few more lines of code, but I
just think it looks cleaner.

That being said I do use DOW of other things. I have a IFS service program
that I use DOW all the time to read files because it returns the number of
characters read. So I guess, as usual, it all depends. I do like having both
though.
