1. PostScript (Computer program language)
First printing, September, 1990
This book is intended to provide a practical, intriguing, and fresh look at
the PostScript programming language. PostScript is a mysterious
language, powerful and cryptic. It is expressive and complicated and yet
surprisingly simple. In order to master a programming language, you have
to learn to think like the compiler or interpreter, and instinctively know
how to solve problems. You develop a “tool kit” of useful approaches,
proven solutions, and techniques. You reach an understanding that is
based on analogy and connections with other things that you know.
This book helps you build a solid foundation of understanding for the
PostScript language. It teaches you to become an expert programmer and
to have confidence that you have written the best possible PostScript
program. It shows you how to combine the elements of the language into
a strong, well-designed, modular program that is easy to develop and
maintain. It is not a problem-solving book, nor simply a reference to the
language; it is a guide to developing programming techniques and to
learning how to use the PostScript tool kit, which is filled with hundreds
of individual operators.
