Postscript

A postscript (P.S.) is an afterthought, thought of occurring after the letter has been written and signed. The term comes from the Latin post scriptum, an expression meaning "written after" (which may be interpreted in the sense of "that which comes after the writing").

A postscript may be a sentence, a paragraph, or occasionally many paragraphs added to, often hastily and incidentally, after the signature of a letter or (sometimes) the main body of an essay or book. In a book or essay, a more carefully composed addition (e.g., for a second edition) is called an afterword. The word "postscript" has, poetically, been used to refer to any sort of addendum to some main work, even if it is not attached to a main work, as in Søren Kierkegaard's book titled Concluding Unscientific Postscript. Sometimes, when additional points are made after the first postscript, abbreviations such as PSS (post-super-scriptum), PPS (postquam-post-scriptum) and PPPS (post-post-post-scriptum, and so on, ad infinitum) are used, though only PPS has somewhat common usage.

PostScript

PostScript (PS) is a computer language for creating vector graphics. It is a dynamically typed, concatenative programming language and was created by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton in 1982. It is used as a page description language in the electronic and desktop publishing areas.

History

The concepts of the PostScript language were seeded in 1976 when John Warnock was working at Evans & Sutherland, a computer graphics company. At that time John Warnock was developing an interpreter for a large three-dimensional graphics database of New York harbor. Warnock conceived the Design System language to process the graphics.

Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a successor.
