Beginning BASIC with the ZX Spectrum (Macmillan microcomputer books)

The aim of this book is to teach programming in the BASIC language, as used by
the ZX Spectrum, to the complete beginner. It is not an '0' level or C.S.E. text·
book, although It does cover practically all the programming skills required at
those levels. Mathematics has been kept to a minimum and therefore arithmetic
functions such as ABS, EXP, LN, PI , SGN and SQR logether with trigonometrical
functions SlN. COS,TAN, ASN, ARC and ATN hal'e not been included,
Each unit is written so that it relies only on infonnation already covered in
previous units. This means that if the reader works through each unit in turn, he
or she will not need to have any knowledge other than that already encountered
in earlier units. If, however, the reader covers the unit out of order. then
difficultIes may be experienced unless he or she has previous experience .
The book is best used with a microcomputer at hand as it is recommended
that the sample programs are typed in. The program listings are direct copies of
tlle screen, thus providing an easy check that the program has been correctly
entered, Each unit gives plenty of opportunity to practise the skills just acqUired
and solutions to the activities are included at the back of the book. It should be
remembered. however, that in programming there may often be several solutions
to a problem and therefore if the readers program works successfully it is just as
acceptable as the solution given.
