Program Logic




DOS System Service Programs

Program Number 360N-CL-453
This reference publication describes the internal
logic of supervisor-interrelated service programs
of the IBM Disk Operating System.
This manual is intended for persons involved in
program maintenance and for system programmers
altering the program design. Program logic
information is not needed for normal use or
operation of the system control program. It is
designed as a supplement to the program listing.
Its effective use requires an understanding of
the IBM System/360 or System/370 operation and of
the IBM Disk Operating System control and service
programs, macro instructions, and operating
procedures. Reference publications for this
information are listed in the Preface of this
manual.
