HyperTalk
     
        A verbose semicompiled language by Bill Atkinson and Dan
        Winkler, with loose {syntax} and high readability.
     
        HyperTalk uses {HyperCard} as an object management system,
        development environment and interface builder.  Programs are
        organised into "stacks" of "cards", each of which may have
        "buttons" and "fields".  All data storage is in
        zero-terminated strings in fields, local, or global variables;
        all data references are through "chunk expressions" of the
        form:
     
        	'last item of background field
        	"Name List" of card ID 34217'.
     
        Flow of control is {event-driven} and uses message-passing
        among scripts that are attached to stack, background, card,
        field and button objects.
     
        {Apple Computer} has taken back distribution and maintenance of
        HyperCard from {Claris} Corporation
