How to Access Fonts

[G. Murdock Helms]

I'm tinkering with some graphics code (just finished the class two
weeks ago), and am interested in finding out what type of fonts are
already defined and known to our 4D70GTX.

Knowing that font 0 is the default font, I tried font(1); and font(2);
which produced a font that looks identical to font(0); but also 
produced the error message
ERROR #92 font : ERR_NOFONTFOUND

(sigh)  Can anybody tell me what I missed and how to access other fonts?
It'd be much appreciated.

Thanks.
