@Janus : i just realized because your code doesn't perform any data scrubbing, anything that's not a positive integer immediately stack overflow due to infinite loop

here's the version that fixes both of those :

function ___(_) { return (_ = int(_)) <= _^(_<_) ? -_<+_ : __(_,_~_,_<_) }
function __(_,____,_____) { return (_ -= (____ += +_____)^(_<_)) ? __(_,_____,____) : +____ }{ print ___($-_) }

This is a correct observation, and I think I've addressed that in my
last post of this sub-thread where I suggested adding a condition to
keep the numbers in the domain of valid numbers.

(BTW, I suggest, in Usenet posts, to quote context to make it easier
to see what you are referring to. Thanks.)
