FOREWORD
If you are a Commodore 64 owner, or are about to
become one, it is probably because you have decided
that this computer offers you more on graphics, colour,
sound and memory.
Because of the potential of the Commodore 64, we have
written a wide selection of programs to meet your needs.
If you are a games player, you will find ample use of
colour and graphics to please your eye and test your
reactions. If you are someone who is interested in
'beating the computer' by working out logical steps, then
the adventure games are for you.
Programmers are catered for with a highly versatile
assembler/disassembler program, which will allow
machine code users to convert hexadecimal to decimal.
They will also be able to save and load machine code
routines to, and from, tape.
To help users understand the graphic symbols, we have
listed the line numbers and given instructions for their
use. W e have also explained sub-routines, so that users
may alter the programs, if they wish, to increase the
speed and complexity of many of the games.
All of the programs in this book have been listed
complete with spaces to improve clarity. Normally
Commodore Basic does not require spaces between key
words and variables or numerical constants and their
deletion will both save space in m em ory and may speed
upthe running ofthe program.
