Wish my code snippet hadn't been snipped, because it did work, without
the parens issue.
$var was intended to be used in some places and $var[n] in others
but I don't.
That said, I'll have a relook again as you might have a point; alnum
still isn't giveing me what I need and I've assued it's been because of
a necessary space in the string, which I thought I'd taken proper care of.

Thanks for the prods.
