Abstract
A system, program and method for interfacing a human user to an indexed field of data from a database. The invention is particularly directed to the definition of a BETWEEN argument in a database query. A ruler is linearly related to the data in the field. Individually movable tacks are positioned along the ruler to define the boundaries of a range in direct correspondence to a range of data from within the field. Dialog blocks are provided for alphanumeric entry and readout of tack location data. In a preferred form, the ruler also provides control blocks which are individually related to the tacks and are suitable to increment or decrement the tack values as relates to the data in the field.
