TABLE DRIVER FOR DISPLAY AND CORRECTION OF DATA

摘要

Data modification and display apparatus for use as an editing device has memory 103 containing a buffer 113 for storing data codes representing data to be modified, control data 115 including a state value 121 for controlling modification and display of data, and an editing table 111 containing editing instruction sequences for modifying the contents of the buffer, for modifying the control data, and for producing display codes; a terminal with a keyboard 109 for providing input codes and a screen display 107 for displaying visual representations in response to display codes; and a processor 105. For each input code received from the keyboard 109 the location of a corresponding editing instruction sequence in the editing table is determined. Editing instruction sequences are divided into sections corresponding to certain state values, and editing instructions including instructions to which the processor responds to altering the state value. The processor responds to the editing instructions by modifying the data codes in the buffer 113, or by modifying display codes applied to the display 107. The sections may also include a section containing instructions to be executed at the beginning of operation of the apparatus, and a section to be executed on termination of operation of the apparatus. More than one editing table 111 may be provided, and programs using data modification and display apparatus may select an editing table.
