PostScript, is a *(programming language) designed to express vector graphic computations for laser printers to render pages.

It is stack-based, like _(FORTH), but with dynamic typing like _(LISP). It has blocks of computations, but without lexical scoping, so for higher-order computations, you must use combinators as in _(Joy).

Variants of PostScript include EPS, PDF, DPS. EPS (Encapsulated PostScript) contains meta-information so that you can embed documents in other ones. PDF (Portable Document Format) modifies the language, so that it is no more a full-fledged programming language, but allows execution and manipulation in a controlled way. DPS (Display PostScript) is a variant of PS for rendering in a _(WIMP)y environment.
