Highlighting and classifying segments on a CRT display |
摘要 |
A graphics display terminal is disclosed having a capability of responding to at least two unique input commands. A first assigns a segment to a group of classes and also removes the segment from membership in another group of classes. A second is a matching condition which requests that all the segments lying within a certain group of classes and/or not lying within another group of classes be identified, the CRT terminal highlighting these identified segments in response to a command from the operator. The second command is called a matching condition. Once all of the segments in a memory are located, which satisfy the matching condition, the operator can direct the terminal to blink or otherwise highlight the identified segments retrieved from memory.
