Control and Service Programs
This publication describes the purpose and funct ~')ns of
the Control and Serv~ce programs of the IBM System/360
Model 20 Disk Programming System (OPS).
The publication is designed to help you use the OPS
Control and Ser~ ice programs to build, run" and main-
tain a disk-resident system. '
The disk-resident system controls the compilation~
assembly. and execution of problem programs. It offers
you many advantages: a core-image library to store your
programs, batch job processing for continuous opera-
tion~ inquiry for access to specific information while
another program is runningr multiphase loading for
particularly long programs, and symbolic addressing of
I/O devices for greater flexibility.
