I've never seen a "BY" modifier although I wouldn't doubt that some BASIC
could have been designed with it. But are you sure you didn't mean
"STEP"?

Remember, C has a goto statement, although I don't think in my nearly 10
years of C programming I've ever used it, although on certain rare
occasions it seemed the easy way out to a sticky coding problem. There is
certainly a sublime satisfaction in designing elegant code with do..while
and while loops (I rarely use for's), but C really suffers from a lack of
a general error trapping mechanism that one can invoke to break out of
loops as required. Sometimes I think goto's are the answer but I can
never find an appropriate way to implement it.
