PREFACE

This manual assum€s the user has read an introductory book on assembly

languag€. It is not intended to teach assembly language. Suggested rcferencis

for assembly languag€ beginners are 6'502Assembll ranguage programmingby

Ladce L€v€nthal and Progamming the 65U by Rodney Zaks (6ee Appendix 8).

The wer should alsoknow how to use the scleen editinq and control features of

(eatures are the same as used in ATARI 8AS|C. Rer.i;w rhe"ATARr BASIC

This manual stafls by showing the structure of sLarementsin assembly

Assembl€r Editor ca:rtridge contains three separate programs:

. ASM (Assembler program) - Take6 the program statementsyou ceate in

the EDIT stepand converts to machine code.

- Hetpsyou trace through the program stepsby running the

program a step at a time while displaying th€ contents of important internal

6502 registers. The DEBUGGERprogram also contains programming

rcutines which allow you io display registers, change register contentsJ

display memory, change memory contents, move memory, ve fy memory,

list memory with disassembly,assemble one instruction into memory, go

(execuie prograd, exit. The disassemblyrouiine is especially usefut ir

rcading and understandingmachine languagecode.

The Assembler Editor cartridge allows you to talk in the mmputer's natural

language - machine language.Assembly languag€programming offers you

f:lsterrunning programs and the ability io iailor programs to your exactneeds.
