Such changes are immediately saved when complete, so typing into a field causes that text to be stored to the stack's physical file. ![]() From the HyperCard runtime's perspective, there is no difference between moving a text field on the card and typing into it, both operations simply change the state of the target object within the stack. Instead, the state of any object in the system is considered to be live and editable at any time. The database does not exist as a separate system within the HyperCard stack no database engine or similar construct exists. The database features of the HyperCard system are based on the storage of the state of all of the objects on the cards in the physical file representing the stack. The layout engine is similar in concept to a form as used in most rapid application development (RAD) environments such as Borland Delphi, and Microsoft Visual Basic and Visual Studio. This way, a stack of cards with a common layout and functionality can be created. Also, HyperCard includes prototype or template cards called backgrounds when new cards are created they can refer to one of these background cards, which causes all of the objects on the background to be copied onto the new card. They place GUI objects on the cards using an interactive layout engine based on a simple drag-and-drop interface. Users build or modify stacks by adding new cards. Users browse the stack by navigating from card to card, using built-in navigation features, a powerful search mechanism, or through user-created scripts. Each card contains a set of interactive objects, including text fields, check boxes, buttons, and similar common graphical user interface (GUI) elements. Cards hold data, just as they would in a Rolodex card-filing device. HyperCard is based on the concept of a "stack" of virtual "cards". It's let a lot of non-programmers, like me, into that loop. ![]() ![]() HyperCard has made it possible for people to do things they wouldn't have ever thought of doing in the past without a lot of heavy-duty programming. The beauty of HyperCard is that it lets people program without having to learn how to write code - what I call "programming for the rest of us". HyperCard was not ported to Mac OS X, but can run in the Classic Environment on versions of Mac OS X that support it. It was withdrawn from sale in March 2004, having received its final update in 1998 upon the return of Steve Jobs to Apple. HyperCard was originally released in 1987 for $49.95 and was included free with all new Macs sold afterwards. This combination of features – a database with simple form layout, flexible support for graphics, and ease of programming – suits HyperCard for many different projects such as rapid application development of applications and databases, interactive applications with no database requirements, command and control systems, and many examples in the demoscene. HyperCard includes a built-in programming language called HyperTalk for manipulating data and the user interface. HyperCard combines a flat-file database with a graphical, flexible, user-modifiable interface. It is among the first successful hypermedia systems predating the World Wide Web. HyperCard is a software application and development kit for Apple Macintosh and Apple IIGS computers. Macintosh: System 6, System 7, Mac OS 8, Mac OS 9
