File No. S370-34 Order No. GC20-1821-3 IBM Virtual Machine Facility /370: Operating Systems in a Systems Virtual Machine Release 6 PLC 17 This publication is for system programmers who plan to use System/360 or System/370 operating systems under the control of VM/370. It is also for VM/370 system programmers who plan to use these operating systems or VM/370 under the control of VM/370. The publication describes those aspects of running operating systems under VM/370 that are common to all systems, and it describes how to use VM/370 functions more efficiently when running operating systems under VM/370. The book also provides system planning and operating considerations when running VM/370, DOS/VS, and OS/VS under VM/370. Many thoughts expressed in this publication are contributions from VM/370 customers and IBM field personnel. As such, these thoughts may not have been formally tested by 18M, and therefore, may prove more usefui for some installations than others.

I I I , VM/370 users made many of these recommendations, and theirl Isuggestions have not been submitted to any formal IBM ~est. As at Iresult, potential users should evaluate the applicability of thel Irecommendations to their installations before implementation. L, _ _ _ __ I Fo~
