As with the Macintosh, the release of HyperCard on the Apple IIGS will create an interest amongst both novice and advanced programmers to learn the tools necessary to build interesting stacks.
HyperCard IIGS Script Language Guide is the definitive description of the HyperTalk language. Even a little knowledge of HyperTalk enables you to customize buttons and other parts of HyperTalk stacks for your own purposes, and you can use HyperTalk to make stacks that you create act the way you want.
To get the most out of this book, you should have read GETTING STARTED WITH HYPERCARD IIGS, the HYPERCARD IIGS REFERENCE, and the HYPERTALK BEGINNERS GUIDE, and you should have used Hypercard IIGS enough to be familiar with its basic features.
Many of the scripting conventions developed in the Macintosh HyperCard environment have been carried over to the Apple IIGS HyperTalk environment. Many existing Macintosh scripts that don't depend heavily on Macintosh specific features can be used on the Apple IIGS with little or no modification.
Hypercard IIGS Script Language Guide includes complete descriptions of the following topics:
* objects - buttons, fields, cards, backgrounds, and stacks
* scripts - message handlers, function handlers, and editing
* handling messages - how objects send and receive messages, the message passing hierarchy, and parameter passing
* naming objects - how to refer to objects in scripts
* values - expression evaluation, number handling, containers, chunk expressions, and operators
* keywords and control structures for handlers
* reference chapters - commands, functions properties
The appendixes include a list of HyperTalk terms, with a description for each term; a list of limits defined in Hypercard, such as minimum and maximum sizes of objects; a command syntax reference, with descriptions of the metasymbols used in the command syntax; and a description of the external command and function interface.
