It seems to me that this is the equivalent of opening
myfile for each
subroutine call, reading every record in the file then closing the
file again.

Yes, that's right.

Although I'm not sure about the reading. Is the whole file
read at the
open cursor statement?

No, but it is read in its entirety at the DoU loop. (FETCH does the
lifting.)

Thanks, Dennis. But if the FETCH was executed more than once, it wouldn't be read in its entirety a second time, would it?

By the way, I didn't think FETCH into *qualified* DS did
quite what we would hope. Perhaps I am mistaken on that.

I didn't even notice. That's going too far! How do you suggest breaking all this to the person who wrote it?
