INFORMATION PROCESSING SYSTEM FOR SELECTING DATA IN RESPONSE TO COMPLEX CONDITIONS

摘要

The system stores and displays data in a table format (14), each portion of data being identified by a record and a field (20-36). When used in an entry edit mode, the data is entered or edited by an operator through a "keyboard". When used in a record selection mode, the system permits, by inputting information keystroke representing a comparison operator and data representing a field value and positioning the cursor within a preselected field (32) of the table format (14), to compare the data stored within the preselected field (32) of each record to the field value in the manner required by the comparator operator.
