OK, that's just cool (no pun intended.)  I was going to read a book 
tonight, but now I guess I'll play around with the f_hex_x function 
instead (at least to start with....then I'll probably poke over to your 
tutorial site, 'cause there's something I forgot how to do, and probably 
not get to bed until 2 a.m. -- you're so cruel. ;-) )
