摘要:
A method to assist the operator of an interactive text processing system to update program modules associated with one of a plurality of text processing programs that have been combined on a two-sided, double-density (2S2D) combined program/work diskette. The method involves creating a new 2S2D combined program/work diskette by transferring the programming modules and other data from the old 2S2D combined program/work diskette so that the transferred programming modules assigned to each data set are recorded in module number order after each data set directory and the data set directories are also recorded in sequential order, and replacing a program module on the new 2S2D combined program/work diskette with a corresponding module from the 1S1D diskette containing the updated programs whenever the "build number" of the corresponding module on the 2S2D diskette is lower than the module on the 1S1D diskette.

A method is disclosed for improving the efficiency of an operator of an interactive text processing system in which a plurality of different text processing task programs are each stored on a different single-sided, single-density (1S1D) diskette so that in the creation and use of a text document involving several different tasks, the operator's efficiency is decreased due to the time involved in inserting and removing each required diskette. The method involves creating a combined program diskette on a two-sided, double-density (2S2D) diskette by sequentially transferring program modules for interactively selected text processing task programs from corresponding 1S1D diskettes under the control of a "Combine" program. The method provides one 2S2D combined text processing program diskette containing all the programs necessary to create and use a specific text document by means of the selected tasks.

The specification discloses a word processing system having a keyboard (10), a display (20), a processor (14) and a random access memory (22) for storing data and programs. The display (20) includes a first text area (24) wherein text entered through the keyboard is displayed. The display also includes a prompt line (26) through which all input between the operator and the word processing system occurs. The system provides deadkey compression wherein the depression of selected deadkeys on the keyboard causes the automatic generation of a required backspace in order to enable the construction of a diacritic character and the display of the constructed diacritic character in either the text display area (24) or the prompt line (26).

An improved text processing method is disclosed which permits spatially related data to be displayed and edited by the same method employed to display and edit conventional text type data in an interactive text processing system which includes a keyboard, a display device, and a microprocessor.
摘要:
A keyboard access system is provided for interfacing a keyboard and the programs of a text processing machine. The keyboard has typamatic function keys, i.e., nontypamatic keystroke information is generated by the keyboard upon depression of a key and, after a short delay, additional typamatic keystroke information is generated as long as the key is held down at a constant rate. The keystroke information represents a key on the keyboard and may also represent the meaning of the key as determined by the state of one or more prefix keys. A keystroke queue is provided for storing keystroke information passing through the keyboard access system. If the keystroke information entered into the keyboard access system is not typamatic, the system will enqueue the information in the keystroke queue and generate an audio feedback signal when the keystroke queue is not full. If the keystroke information is typamatic, the keystroke information will be compared to a table of valid typamatic function keys. If a comparison does not exist, the keystroke information is discarded. If a comparison does exist and the meaning of the key is acceptable, the keystroke information is enqueued if the preceding keystroke enqueued is no longer stored in the keystroke queue and discarded if the preceding keystroke is enqueued and currently stored in the keystroke queue and also represents the key to prevent excess information from being stored in the keystroke queue. This prevents operator overrun while using keys such as the vertical and horizontal cursor. In addition, the provision of a slow typamatic function rate permits the operator to read the text on a display while using a vertical cursor key.

A ghost cursor indicates the relative horizontal position on a display screen associated with a printed document rendition of the displayed text and control codes. In a normal, or hidden codes, mode of operation the ghost cursor, placed on an escapement scale line, is vertically aligned with a text cursor which is positioned adjacent the displayed text code which defines the present point of operation. In the all codes mode, all text and control codes (such as required backspaces, tabs, etc.) are displayed. In the all codes mode the ghost cursor indicates the relative horizontal position on the display screen of the code associated with the text cursor, with forward or reverse escapement indicated by the control codes taken into account.
摘要:
Multiple virtual images are built on a display screen of a text processing system by a display access method (DAM) program running interrupt identified service programs. Each of the service programs is provided with stack memory elements for retaining data to run the program. Each of the service programs is run by the DAM program in accordance with priority interrupts with a higher priority interrupt having immediate access to the DAM program. A service program having a low priority interrupt that is being run by the DAM program will be stopped by the occurrence of a higher priority interrupt with the data and address information of the interrupted program retained in the stack memory elements. The service program of the higher priority interrupt is then run and when ended the DAM program retrieves the data for the lower priority program to return to the point of interruption. This program of the lower priority interrupt is then run to an end if not again interrupted by a higher priority interrupt.

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.
摘要:
Operator keystrokes are processed in a text processor system to move a cursor on a display screen in either a vertical or horizontal direction or both without limitation as to the location of text. Keystroke data is processed under the control of programs stored in a random access memory. For a cursor motion, 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 and the programs equate a contextual cursor address with a spatial cursor position. 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 a cursor at an identified position in text.
摘要:
A text processing system includes a first external storage area for text documents, an internal text storage buffer where, inter alia, edit operations are performed, and a third storage area in which text is formatted for display. The area for formatting text for display is related to the internal text storage buffer by a table containing pointers to the text storage area, one for each line to be displayed. The pointers are expressed relative to a single known address, that of the start of the line in the text storage buffer containing the point at which the edit operation is to occur.
