Abstract
An improved method is disclosed for assisting the operator of an interactive text processing system. The method assists the operator in entering interactively selection criteria to be used in selecting records from the existing file. The improved method involves displaying to the operator the header portion of the existing file, along with a predetermined number of "qualifying rows" in response to the operator having identified to the system the task to be accomplished and the name and the location of the existing file in the system. The method further involves movement of the cursor vertically and horizontally to row and column positions for entering of the selection criteria. After entering criteria into the displayed rows, the next operation of the cursor down key while in the last row is interpreted as an instruction to the system to add an additional row so that another "logical OR" selection criteria can be added to the previous criteria.
