Thinking in PostScript

Thinking in PostScript - The book is a result of Glenn Reid's years trying to teach people to write PostScript programs, during which he discovered that people tended to try to make PostScript "look like" other programming languages they already knew. There is even a chapter in this book entitled "PostScript Is Not Like C", because it is really a very different language, and one must learn to "think" in PostScript in order to be a good programmer.
