MIXED PITCH DISPLAY |
摘要 |
<p>MIXED PITCH DISPLAY Operator keystrokes are processed in a text processor system to put characters and symbols on a fixed pitch display screen without limitation as to other size characters or symbols on the screen. Keystroke data is processed under the control of programs stored in a random access memory. For a mixed pitch display, the random access memory of the system is structured to include a text storage buffer and a display control block both interconnected to an applications program and a display access method program. Data is stored in the text storage buffer in an unformatted configuration in a mixed pitch arrangement and the programs evaluate the data to display characters and symbols with correct character pitch. The programs also draw a scale line on the screen to provide character information to the operator. After running the display access method program in accordance with application program commands, a refresh buffer provides display signals to visually present by means of the display screen characters at an identified position in a mixed pitch format.
