QUALIFICATION SYSTEM FOR INPUT KEY ARRAY STRUCTURE

摘要

PURPOSE:To qualify a key relation structure from an input key array and to dividing the key array into groups containing plural keys by providing a storage means for information which represents an object of inquiry and an area to be handled by structure and a means which makes a level decision between adjacent keys by referring to the stored information successively. CONSTITUTION:When a key input processing function 2 is started, one input keyword is acquired to decide whether input keys are all processed or not and when not, index keys of stored key classification information 1 are collated to give table constitution ID corresponding to a key for finding coincidence to said input key. Namely, the key classification information 1 and table constitution hierarchy information 3 are put in different tables by meanings and purposes, but a table condition ID, a table ID, and level information are put together in a one group of pieces of information for an index key, thereby improving processing efficiency. Further, a specific position of a code representing the table constitution ID, i.e. head character is used as the table ID to reduce the necessary memory capacity for processing information.
