File No. S360-20 Order No. GC28-6551-16 OS Systems Reference Library IBM System/360 Operating System: Storage Estimates OS Release 21. 7 This publication is intended for three types of users: system planners, system programmers, and problem programmers. It contains instructions, formulas, and figures that can be used to estimate the main and auxiliary storage requirements for any machine configuration, control program, and control program option of the IBM System/360 Operating System. Main storage requirements are divided into two categories: fixed main storage and dynamic main -storage. Fixed main storage contains the resident portions of the control program and the optional services and load modules that can be made resident to improve the performance of the operating system. Dynamic main storage is the area where program processing is done. Each type of user can use this publication differently.
