For example, if a new, superior assessment methodology is available, the service provider should be able to make use of it immediately without abandoning the technical information in the database. HyperHome Resource is designed to overcome the problems of closed systems. The program is written for Hypercard, the hypermedia database tool that comes with every Macintosh computer. Cards can contain a mixture of graphics, sound and text. Access to them is obtained through a menu card.
Stacks are sets of similar cards.
HyperHome has two basic stacks, problems and recommendations. The stacks are organized into sections with 5 types of problems and recommendations. Scrolling windows allow the user to scan through items rapidly. By pointing and clicking with a mouse or other interface device, one can go forwards or backwards through a stack, jump to different locations or access different stacks. The most important button however, links each problem to related recommendations.
