Preface

At a time when C is all the rage, you have purchased an assembler. But

don't be bothered by the self-assured talk of dyed-in-the-wool C fans. C

is certainly a machine-oriented high-level language, but C is still a

high-level language. Even though manufacturers of C compilers would

like to tell you that C is as fast as assembly language, the fact cannot

be denied that assembly language is absolutely the fastest way to

program a computer.

program, writing it in C doesn't look so bad, assuming its floating

point routines were written in assembler. But normally a C program is

True, when you a have to do a lot of floating-point calculations in a

always noticeably slower than an assembly language program. The

reason is that the C compiler uses only a small set of the machine

language commands available. As an assembler programmer you have

the ability to obtain full use of your processor.

You often hear that you couldn't write any large programs in assembly

language, but this doesn't seem true anymore once you know that

AssemPro Amiga was written completely in assembly language. And it

certainly isn't small, is it?

The processors in the 68xxx family are very well suited to

programming in assembler. They offer a relatively compact, yet

powerful instruction set, so you don't have to remember too many

commands, and a large number of addressing modes, which together

with the fifteen CPU registers simplify programming considerably.

To further simplify working in assembly language, there are libraries

on your assembler disk which allow you to call almost any operating

system function with a single command.

After so many positive things, there are still a few things to be

mentioned:

AssemPro Amiga is an assembler. In order to use it, you must know

how to program in assembly language. If this is not the case, you

should get an introductory book and learn this language. If you don't

have any programming experience at all, then maybe you shouldn't

start with assembly language. Try Pascal or Modula instead.

iii

Just as AssemPro Amiga isn't designed to teach assembly language

programming, it is not intended as a tutorial about the Amiga operating

system either. If you don't already have books about the operating

system, there are many available.

In conclusion I would like to thank Hannes Riigheimer and Uwe Braun

who did some of the various work for me and also supported me in my

efforts, as well as Jochen Schneider, Barbara Schutte and Gudrun Debus

for extensive editing of this manual.
