Re: string.gsub and its need for variables..

Thankyou :) I like the brackets, that's a neat answer and the one I'll use. The function is ok too, though I'd only do that if I wanted further modification, probably.
That said, isn't it strange that there should be special requests for a minimum default? In most things in life we might only want extra information if we ask for it, and Lua, by doing the reverse of this, seems to risk losing the easy and clarity it is so good at.
