PREFACE
500 POKES PEEKS 'N EXECS FOR THE TRS-80 COLOR COM­
PUTER is a unique book Inasmuch as it contains information
which Is of utmost significance to any programmer. This Information
Is generally not found in one place and the people
who know aft! hesitant to divulge thls valuable arid confidentlal
information. It has therefore taken a great deal of
research to pre~r. this book.
This book will unravel the POKE. PEEK ana EXEC commands
of the Color computer to helpyou gain the power of Assembly
Language thru ~. It includes vanoos comrTllflds relating to
almost all the aspects of the Color COmputer programming. In
order to help you reICh greater heights In successful programming.
a number of Utlllty Routines Uke AUto!tartlng your
Basic programs from cassette, Dlsabllng vanous Color/EeB/Disk
BasIc commands. and Key- and Error-beep IIave
been included.
Besides the utlllzatlon of the bask: knowledge of the inner

HOW TO USE THE BOOK
SOO POKES PEEKS 'N EXECS FOR THE TR5-8O COlOR COM­
PUTER ha been ~MIn a style that can be NSlly followed
by a MOPhyte as well as a proftsSiooal programlMf./t follows
a lOgical wquence of ~ groups ~ on the different
Systems - e-tte and DlsII System,. 0Wt System onl)'.
Pnnt«. and64K cassette 8. Disk S)'sums.
EKfl POKE. PEEK 8. EXEC command is followed by the ensuing
RESULT and detailed REMARt

vii
FOR CAS5ETIE AND DISK SYSTEMS
Most of the commands listed under this section are compati·
ble with 16K/32K/64K Cassette and Disk Systems. However
certain commands are not compatible with disk systems and
are so mentioned in the REMARKS. Similarly. most commands
are compatible with both Color Basic and ECB. While some are
exclusively for Color Basic OR ECB OR Disk Basic. These are
specifically mentioned in the RESULT or the REMARKS.
Utility Routines
One of the important features of this book is to help you
utilize various POKE, PEEK and EXEC commands in different
utility functions. These utility routines should have a statement
number and Should be placed in the beginning of your
Basic program.
Certain Color and ECB commands disables have been included
under the utility routines (Disk Commands Disables are listed
under the section 'FOR DISK SYSTEM ONLY'). In order to
disable various Color Basic/ECB/Disk Commands. first type in
the BASE Command Pokes. The BASE Command Pokes for Color
Basic/ECB/Disk Basic are given in the BEGINNING of each
group and are followed by individual pokes which disable a
SINGLE command. Once you have typed in the BASE pokes for
a group (Color Basic/ECB/Disk Basic), you may use ONE or
MORE of the individual pokes to disable various commands.
NOTE, DO NOT REPEAT THE BASE POKES FOR EACH IN·
DIVIDUAL COMMAND DISABLE POKE, The same applies to the
KEY·DISABLEs, except that you may use only ONE of the in·
dividual Key·Disable pokes following the BASE pokes.
FOR DISK SYSTEM ONLY
All Commands listed under this section require 16K/32K/64K
Disk System and are only compatible with ECB.

vIII
FOR 64K CASSETTE AND DISK SYSTEMS
All commands llsted under this :>eetlon require a 64K Color
Computer and the 64K All RAM MODE given In the beginning
of the :>eetlon. The command to set the All RAM MODE
should have a statement number and should be 'RUN' to set
the 64K ALL RAM MODE. The command to set the ALL RAM
MODE should preferrably be given in the beginning 01 your
Bask program.
GAMES
The commarnlS listed under thls:>eetlon help you to get more
plays on 23 different arcade games. The individual commands
should be typed In AFTER "(C)LOAOM'lnll the arcadeijame and
BEFORE typing ·EXEC'. The names of the variouS arcadegames
used in this section are Trademarks of different com·
panles. and have been Included for the sake of easy comprehension.
