You
can download the book as pdf document. For reading and printing Pdf-files you need the
free Adobe
Acrobat Reader. The text corresponds as closely as possible to the original
printing, but owing to the different troff versions used (respectively
Unix-V7 Troff and
Groff), there are differences in the line breaks.
The original page breaks have been preserved. Also, printing errors have been corrected, and the figures have
been remade with Pic and
Grap, which
were not available when the book was written. The data can also be downloaded as
Lotus WK1 files.
