LDA #-1 *should* be the same as LDA #255, but in 2.20.10 it is foiled  
by a type problem internally (signed vs. unsigned comparison) so the  
assembler barfs up an error message. At least that's true if I am  
doing my experiments correctly...

(Take this with a grain of salt, I haven't been hacking dasm for very  
long, so who knows. Actually, Thomas might know the definitive  
answer? :-)

Cheers,
