DATA INPUT METHOD AND SYSTEM WITH MULTI-SUB-FIELD MATCHING OF USER ENTRIES INTO A GRAPHICAL INPUT DEVICE

A current set of user-selectable choices is associated with a displayed graphical input device, which is used to select a value of an input parameter. Each user-selectable choice has at least one pair of information fields separated by a delimiter and each information field comprises sequentially ordered characters. A search for a matching entry to assign to the input parameter is carried out as the user enters each of a sequence of characters, and if a match is not found in a first information field, then (or simultaneously) it is sought in a different information field, also on the basis of the character-by-character user entries.
