ABSTRACT:
A character display system including a storage device having a number of lines of storage locations greatly exceeding the number of lines to be displayed, and a processing system preferably implementing key functions for the maximum effectiveness and convenience of an operator with very high order discretion in producing text, such as a news editor for an on-line news dissemination system. The processing system is thus highly user oriented so as to provide minimum distraction from creative mental effort, and to this end the aim is to accommodate continuous typing with minimum visual reference to the display. To this end, with automatic carriage return, there is provided a space delete operation with reference to the first character location of a new line, and automaic elimination of null codes by left justification in response to typing with respect to any new line. As a reflection of the great discretion of the operator, an insert mode of the processing system will immediately provide a substantial number of empty spaces such as a full line whenever a character to be inserted is generated with respect to a location of existing text. Entry marker control is by means of keys having only the normal typing modes, so as to avoid any distraction or need for special attention by the operator in adjusting entry marker location. Another expression of deference to the operator is the provision of tab points which once set in a given line are automatically established at the same lateral positions in all succeeding lines of the buffer assigned to the terminal. Similarly, tab points are moved with data, and a reset tab function also serves to delete all tab points following the current line. Fields of data are moved under keyboard control with automatic deletion of the data from its previous location. At the completion of an insert or move function, the resulting data is automatically left-justified as appropriate, and the various automatic features of the processing system are operative in the insert mode as well as in the normal text generation mode.
