Abstract

Fig. 1 shows data placement within a memory device such as a 16K-byte EPROM. It illustrates a way to compactly store and reference a set of messages (the data) for a CRT display system where each message is sufficient to define all the characters which simultaneously appear on the CRT. (Image Omitted) Each message is initially defined using an instruction set which includes the text of the message plus controls for formatting (such as spaces, hard line endings, and indentation), punctuation, and presentation attributes (such as blinking, highlighting, reverse video, and underlining). Controls are also included to allow the enabling/disabling of conditional information within a message so that a single "message" may serve multiple situations.
