    Abstract
    In a large-scale classification system, such as UDC, users are often troubled during the process of finding a relevant classification number for his concept or term and producing (combining) a final compound classification number. UDC tables are now computerized in many language editions, and the MRF had released as a master file (database) by the UDCC in 1993. In this paper, a system function is described for a man-machine interactive system to support compound UDC number assignment, and the necessary re-organization of UDC data/file formats are considered for the use in the automatic classification number combination
