r ------, IClass I 1-------1 User and Function
Al The class A user controls the pi Any2 , VM/370 system. Class A is assigned to the user at the VM/370 system console during IPL. The primary system operator is responsible for the availability of the VM/370 system and its Gommunication lines and resources. In addition, the class A crser controls system accountinq, broadcast messages, virtual
machine performance options, and other command operands that
affect the overall performance of VM/370. The system
operator controls operation of the real machine using the system control panel and console device. The class A system operator who is automatically logged
on during CP initialization is designated as the primary
system operator. QEerator: The class B user controls
allocation and deallocation of all the real resources of the VM/370 system, except those controlled by the primary system
operator and spooling operator. The class C user updates certain
functions of the VM/370 system. The system programmer can modify real storage in the real machine. QEgtgtQI: The class D user controls spool data
files and specific functions of the system's unit record
equipment. !ngly§t: The class E user displays the contents of
real storage, performs the functions required to generate systems and discontiguous saved segments, and controls
the collection and recording of performance measurement data.
This class of user can display the contents of specified real storale areas on the virtual operator's console or on a
spooled virtual printer, but cannot modify real storage. The class F user obtains, and examines, in detail, certain data about input and output
devices connected to the VM/370 system. The service representative can establish intensive recording mode for one device at a time and can cause the recording of
repressable machine check errors to be initiated or resumed. Q§gr: The class G user controls functions associated
with the execution of his virtual machine. A general user
cannot display or modify real storage. The Any classification is qiven to certain CP commands that available to any user. These are primarily for the
puroose of gaining and relinquishing access to the VM/370 system. , H Reserved for IBM use. 1 ,1Described in the 12Described in this publication.

CP Commands Accepted from Each User Class The information should help the user interpret Figure 4. The
table every CP command but it does nQ!' contain every operand.
Fiqure 4 2n!y lists those operands that fall into these categories: • The operand for a command is unique to one particular privilege
class; the operand cannot be specified by the same command when the
commanj belongs to another privilege class. An example is the TRACE operanj which is only valid for the class F NETRORK command, but invalij for the command in class A or B. The operand is available for a command in several privilege classes,
but one or more privilege classes exist that do not support the
operanj. example is the SET command which has an AFFINITY operand
available for class A and G commands, but not in the B or F class. commanjs listed without operands indicate that any valid operand associatej with the command can be specified in any class the command belongs t.:::>. The operands listed in the table in lowercase indicate either an or numeric specification is required.
These lowercase operands include user identification (userid),
virtual ajdress (vaddr), real address (raddr), and device type (device).
For example: userid vaddr
