Best ASM Programming book for Apple

[Mookie Harrington <ch003i@mail.rochester.edu>]

Hello all!

I was interested in recommendations for the best assembly programming book
for the Apple ][ (particuarly //e).  I have two in my collection, one
which is specifically addresses to turning Pascal programs into Assembly,
and one which is entitled something like "Apple Machine Code" (red book,
spiral binding).  I'm taking a class on assembly right now at school, and
I hope to start doing some serious programming on my Apple when I get home
this Summer.
Also, I know that the //e allows you to enter some sort of Machine Code
assembler with the "!" command.  Is that so you can type in ASM commands
directly, instead of having to use the 00-FF codes?
I'm sure I used some incorrect terminology in this post, so please feel
free to correct me.  Much appreciated!
