I can't help you much there, none of the books I read were that great for
beginners. I was pretty much limited to my libraries selection at the
time.

 I'm taking a class on assembly right now at school, and

Well, I took an assembly course two years ago, and aside from already
knowing how to do hex and binary math/conversions, twos compliment
concepts, and a little about logical ANDs and ORs, my knowledge of Apple
II assembly programming wasn't all that great an assest in an ASSIST
Assembly course. Don't expect it to give you that much of an edge.

Ah, the mini assembler. It's limited in that you have to hand-code the
memory references. No labels, no macros, no equates, no symbols. YOu can't
do "JSR MLI", you have to do "JSR BF00", and there is no db thing. To call
ProDOS, you have to do a "JSR BF00" and then drop out of it and manually
specify the rest of the call.
You're better off getting a real assembler that can handle labels and
stuff. Not to mention libraries.
