A Program System for the Automatic Issue and Revision of Illustrated Parts Catalogs

The illustrated parts catalog issue-revision system is a group of computer(IBM 7090) programs that can be used to generate a new parts catalog or revise an old one. The basic functions of the system are to process all input data, to merge input data with a history tape of the previous level catalog in case of a revision, and to paginate the catalog. Pagination procedure includes placement of illustration pages and titles in proper relation to their associated lists; formation of revision pages to accommodate overflow data; placement of list captions; deletion of obsolete lists and associated illustrations; placement of running heads and feet, including full sheet deletion notices and revision date; and the assignment of page numbers.
