Clever. I don't like the conditional either, but you are also
unnecessarily reinitializing sep every time through the loop. With the
goto I avoid both the conditional and the reinit.
In a way I guess I'm creating a new control structure (at least new to
me). Heck maybe I'll add it as a full bonified control structure in my
WP-2 Forth. Forth doesn't have goto, but it gives you the tools to
create your own control structures, so a good trade-off.
BTW, I think you mean *aryp not &aryp
