Y2S-6606-0 Program Logic IBM System/360 Operating System Catalog Management Program Number 360S-DM-50S This manual provides detailed informa- tion on catalog management routines. These routines record identification of volumes used by data sets by maintaining informa- tion in logical records called indexes. The functions and structures of the rou- tines are described, as are their relation- ships to other portions of IBM System/360 Operating System. This manual also des- cribes the structure Of catalog data sets that contain the indexes processed by catalog management routines. It is intend- ed for use by persons involved in program maintenance, and system programmers who are altering the program design. Program logic information is not necessary for the use and operation of the program; therefore, distribution of this publication is limited to those with the aforementioned require- ments. RESTRICTED DISTRIBUTION--SEE ABSTRACT PREFACE The information contained in this manual is intended for programmers engaged in maintenance of catalog management routines. Because of the close relationship between catalog management and other portions of the control programs of IBM System/360 Operating System, many details in this manual are helpful in understanding overall system operations. This manual is arranged in two sections. The first describes the structure of a catalog data set and how indexes and volume control blocks are recorded in such a data set. The second is the description of the catalog management functions and the inter- nal logic of the routines that perform the functions. The manual is a detailed and comprehen- sive guide to the internal structure and functions of the catalog management rou- tines. It is designed to be used in conjunction with assembly listing and, con- sequently, does not discuss program struc- ture at the machine instruction level.
