Yes, so you either have to trap the scalability with a flag (see source below) or look out for that -1 value in the first element of the AFONT() array.

>>>Is there a way to find out what is the smallest size for a font? I've been experimenting with resizing, and if I make the form too small, the fontsize goes to an illegal value. I'd like to know what is the lowest allowed so I can put a check for it. I want this to work for every font, though, so unless they all have the same lowest value, I need some way to check based on the font.
