HyperTalk


HyperTalk

A verbose semicompiled language by Bill Atkinson and DanWinkler, with loose syntax and high readability.

HyperTalk uses HyperCard as an object management system,development environment and interface builder. Programs areorganised into "stacks" of "cards", each of which may have"buttons" and "fields". All data storage is inzero-terminated strings in fields, local, or global variables;all data references are through "chunk expressions" of theform:

'last item of background field"Name List" of card ID 34217'.

Flow of control is event-driven and uses message-passingamong scripts that are attached to stack, background, card,field and button objects.

Apple Computer has taken back distribution and maintenance ofHyperCard from Claris Corporation
