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

HyperCard

An early Macintosh application development system from Apple that was one of the first visual tools for building hyperlinked applications. "Stacks" of "cards" were built that held text, graphics, sound and video with links between them. Complex routines could be embedded in the cards using the HyperTalk programming language.

The HyperCard program had to be resident in the computer to run the stack (the program). Although HyperCard compilers were available from third parties, a runtime engine was eventually included in the stack so that HyperCard did not have to be installed on the target machine. HyperCard came out in 1987, and although it was used to create myriad applications, and many programmers loved it, Apple stopped enhancing it after the turn of the century and stopped selling it in 2004. See hypertext and LiveCode.

I then ported the rulebases both as separate entities and as one entire overview to metaCard's Transcript scripting language, which was derived from Pascal / HyperTalk and also uses quasi-English for its instruction.
That experience, together with the history of programming languages during the past 30 years--from Basic to Pascal, from Logo to Smalltalk, from HyperTalk to Lingo--convinced us we could never come up with a language that would work for novices.
On the technical front, Electronic Publishing on CD-ROM covers electronic document authoring systems (e.g., Adobe's Acrobat, Macromedia's Director, Apple's HyperTalk) and discusses traditional and emerging document standards and formats (e.g., SGML, HTML, Java), as well as physical disc standards (e.g., ISO 966O, HFS).

Some tools and languages, such as HyperTalk and Visual Basic, indicate that many people will become programmers if the barriers are lowered to learning the language.

Languages such as "Hypertalk" (Apple Computer, Cupertino, Calif.) and "Plus" (Spinnaker Software, Cambridge, Mass.) allow a programmer with even limited experience to write complex programs that would have been very difficult to write with the earlier linear languages.

Appendices include the HyperTalk scripts for these stacks, which can be modified to suit other networked information resource activities.
It is somewhat of a moot point to argue over what HyperCard might have been, but it was indeed possible to create HyperCard stacks without having to touch HyperTalk (the scripting language inside HyperCard).
