Dear Friends:

 I am looking for copies of the following books:

6809 Assembly Language Programming by Lance Leventhal

The MC6809 Cookbook by Carl Warren.

I understand that both of these are out of print. If you have a copy which you
would be willing to sell, please let my know as to price, etc. If there are any
other book that you could recomend, please let me know. I have Bill Barden's
and Laurence Telpolt's books already. This leads me to several questions which
I would like to raise.

These last two books were written for assembly language programming under
RS-DOS. I know that RS-DOS assembly language programming is different from OS-9
assembly language programming. Why? I know that under OS9 Level 1 and 2 code
must be position independent. Would a program written un RS-DOS work under OS-9
if it were written as position independent code? Finally is it possible, or
worth it, to rewrite position dependent code to position independent code? Or
would you have to take each section of position dependent code and convert to
modules which could then be managed by some sort of 'skeleton program.' (I have
absolutely no idea of what I am talking about, but it sure sounds impressive
anyway.)

I know that this is a lot to ask, but if anyone has some sort of bibliography
which would help me learn this, perhaps a course outline or reading list, etc.,
which they would be willing to share, please let me know. I really would love
to learn more about programming, but in my present obligations, I am not free
to be able to take any college courses, so I have to do this on my own.

I look foreward to your replies.

With all best wishes,

Br. Jeremy, CSJW
