There was a lot of 'bad mouthing' of iter, leave, etc. yesterday.  How
would you get out of a DOW 0=0 without using them?

Why would I say 'Do Forever' unless I meant it?

I don't code infinite loops.

Part of self-documenting code is the 'invariant' of the do loop; that is, the
explicitly stating the conditions required to end the loop.

To say 'Do Forever' and the LEAVE/ITER is to say 'I'm going to loop
for an indeterminate
amount of time, and then randomly execute a GOTO'.

In my opinion, of course.


It is not my intention to 'bad mouth' the GOTO/LEAVE/ITER constructs. If I ever
need one, I will use it. I have just never needed one.
