ACKNOWLEDGEMENTS
Designing a programming textbook is always difficult. Designing it so that it will teach
elementary programming as well as advanced concepts while covering both hardware and
software aspects makes
it
a challenge. The author would like to acknowledge here the
many constructive suggestions for improvements or changes made by: O.M. Barlow,
Dennis
L.
Feick, Richard D. Reid, Stanley E. Erwin, Philip Hooper, Dennis B. Kitsz,
R. Ratke, and Jim Crocker.
A special acknowledgement is also due to Chris Williams for his contribution to the
instruction-set and the data structures section.
Any additional suggestions for improvements or changes should be sent to the author,
and will be reflected in forthcoming editions.
Several tables in Chapter Four showing hexadecimal codes for the Z80 instructions
