Declined do i=1 to 10 by 0

[vefatica]

That leads to a never-ending do loop. I know it's a dumb thing to do, but this will do the same thing if DELTA is not defined:

do i=1 to 10 by %delta

and that's a little less dumb.

Perhaps there could be a check for the increment being 0.

I've done that a time or two myself, usually as I=0 to 1 BY 0. It's an easy way to create an infinite loop at the command line.

I suspect this would be a breaking change, as I know some people modify %delta on the fly inside their loop.
