File No. S360-36 GY28-660S-4 Program Logic IBM System/360 Operating System Introduction to Control Program Logic PrDgram Number 360S-CI-505 360S-DM-S08 This pUblication describes the components of the primary control program (PCP) configuration of IBM Systern/360 Operating System and indicates the program logic manuals that describe these components. It con- tains general descriptions of the organization of the control program in both main and auxiliary storage, the flow of program control during a job step, the flow of control for supervisor operation, and the processing for input/output operations. The appendix contains the names, numbers, and macro instructions associated with the IBM-supplied SVC routines. Program Logic Manuals are intended for use by IBM customer engineers involved in program maintenance, and by system programmers involved in altering the program design. Program logic information is not necessary for program operation and use; therefore, distribution of this manual is limited to persons with program main- tenance or modification responsibilities. Preface This publication is an introduction to of CPU control for various operations are the logic of the primary control program exameles of typical uses of control program and to the program logic manuals t~t~ f~c~lit
