In fact, whatever occurs to the terminating value within the loop has no effect. In other words you can change the value of the terminator via an assignment and without impacting the number of iterations. Apparently (I checked) this has been the case ever since at least 2.5. It also explains, in part why FOR...ENDFOR loops are faster than DO WHILE...ENDDO.

Okay :) What you said did make sense to me when I saw it, though, because, as you say, some other languages do this...I recall learning that somewhere (was it C?)
