Abstract

Disclosed is a procedure for minimizing system interrupts when using a word processing editor on a data processing system. One of the most significant concerns with putting text processing on a data processing system is the negative effects on the overall system performance. The amount of text which can be displayed at each terminal is limited. With a system having a plurality of terminals, it would thus be necessary to continually go back to the host computer in order to be able to display quantities of text. It is quickly realized that any time the Enter Key is depressed, it is going to take time before editing can continue.

Large Field Text Entry and Revision for Optimizing Performance

Disclosed is a procedure for minimizing system interrupts when using a word processing editor on a data processing system. One of the most significant concerns with putting text processing on a data processing system is the negative effects on the overall system performance. The amount of text which can be displayed at each terminal is limited. With a system having a plurality of terminals, it would thus be necessary to continually go back to the host computer in order to be able to display quantities of text. It is quickly realized that any time the Enter Key is depressed, it is going to take time before editing can continue. Thus, because of the inefficiency of system performance when the Enter Key is pressed, the best way to optimize a word processing editor is to provide some technique which will allow the operator to minimize the number of interrupts. The basic idea is to provide a very large input or work area on the terminal screen. Basically, it should be the size of the entire display screen. The operator is then able to key into the entire area until it is full and then can continue onto the next display. Once the operator requests a paragraph to be revised by placing the cursor on the line of the paragraph that should be brought to the top of the display, and then pressing the "Revise Paragraph Command Key", the paragraph is expanded as shown in Fig. 1 to cover the entire display.
