Apple Macintosh software which allows the creation of hypermedia.

An environment that is scriptable with its own native HyperTalk or with any OSA language.

a product developed by Apple, originally in 1987, to make it easy to prepare hypertexts and hypertext applications, which build upon the concepts of buttons, fields, cards, and stacks. The HyperTalk scripting language follows object oriented programming principles.

system software: An application for creating databases, utilities, presentations, and other kinds of applications. If you have a Mac, you probably have it (or at least its sibling, the HyperCard Player) so stop reading this glossary entry and go play with it for a while. Documents created with HyperCard are called "stacks" (of cards, get it?).
