AT9-81 016 A METHOD FOR AUTOMATIC FIELD WIDTH EXPANSION IN A TEXT PROCESSING SYSTEM DURING INTERACTIVE ENTRY OF DISPLAYED RECORD SELECTION CRITERIA Abstract An improved method is disclosed for entering field dependent record selection criteria into an inter- active text processing system which also processes spatially related data that is stored in the system in vector formatted records. In the process of identify- ing stored records which meet certain criteria, a qualifying frame is displayed consisting of a header row and, for example, three qualifying rows. The header row includes the field names and the qualifying rows are blank, except for the vertical lines depict- ing field boundaries. Selection criteria are entered into the system by positioning the cursor to the appropriate row/ column intersection and entering the selection data for that field. Criteria entered in different fields in one row represent a "logical AND" selection, while criteria in different rows represent a "logical OR" situation. The improvement involves the automatic expansion of the field boundaries of the selected field in both the header row and qualifying rows when more space is required to enter, for example, lengthy qualifiers into the field, a number of qualifiers which are ORed together, or different spellings of the same qualifier. The expansion results automatically in accordance with the relationship of the end of da a position to the right field boundary marker position to move repeti- tively the marker a fixed number of character posi- tions, for example, five, towards the right edge of AT9-81-016 the display, and, when additional space is required, to shift repetitively the field name and entered data to the left five character positions -- therefore, providing an additional five character positions at the right edge of the field after each shift. The five positional left shift process continues as new data is entered, even though the initial data is moved off the screen, until some predetermined limit is reached. Alternatively, if additional space for the entry of data is required when the right field boundary coincides with the right edge of the screen, a hori- zontal line segmenting operation may occur to position the left field boundary at the left edge of the screen.
