THE CATALOG INPUT/OUTPUT SYSTEM

Abstract

A complete definition of the format used for catalogs on magnetic tape and a description of the routines of the Catalog Input-Output System. Catalog maps, catalog data, and tape labels are written as logical records in a specially designed blocking format. Beginnings and ends of blocks, physical tapes, and catalogs are explicitly marked. The Catalog Input/Output System offers a variety of input/out unit-control operations in addition to the commands for reading and writing data in catalog format. The reading and writing commands are implemented on three levels: Level III handles individual data; Level II reads and writes logical records; and Level I processes blocks of information. (Author)
