Abstract
PURPOSE:To speed up the data retrieving by registering data after adding a specific code to a port serving as a key in the data. CONSTITUTION:A data storing memory 5 consists of an NTEXT which manages the number of stored data and a data TEXT. Each TEXT is constituted of an LEN which manages the data length and the actual data DATA. The DATA contains the underline codes added to the parts equivalent to the keys. In such a constitution, an extra key field is not required and only the data having the specific codes are compared with keys. Thus the data retrieving speed is increased compared with the matching operation performed for each string. Furthermore the retrieving actions having no relation with keys are never carried out.
