READS is the total number of page reads for this user since he logged
on or since the last ACNT command was issued for his virtual
machine. WRITES is the total number of page writes for this user since he logged
on or since the last ACNT command was issued for his virtual
machine. DISK is the current number, taken at an instant of time, of virtual
pages allocated on system disk paging space for this user. DRUM is the current number, taken at an instant of time, of virtual
pages allocated on system drum paging space for this user.
The second line of the response gives user CPU usage and accumulated I/O activity counts since logon or since the last ICNT was issued for
his virtual machine. VTIME is total virtual time for the user. TTIME is total virtual and simulation time for the user. SIO is the total number of nonspooled I/O requests issued by the
user.
RDR is the total number of virtual cards read. This value is
obtained from spool file control information. The total number
of cards to be read is incremented once to the RDR=value at the
start of each file read operation. PRT is the total number of virtual cards printed. This value is
obtained from spool file control information. The total nu=ber of lines to be printed is incremented once to the PRT=value at
the end of each file print operation. PCB is the total number of virtual cards punched. This value is
obtained from spool file control information. The total number of cards to be punched is incremented once to the PCH=value at
the end of each file punch operation.

aa is one of the following: E1, E2, Q1, or Q2, indicating the
eligible lists or queues that are occupied.
bb is one of the following status indicators: RU current RUNUSER in uniprocessor aPFlications. In attached
processor applications, RU means current RUNUSER on the
main processor.
RA current RUNUSER on the attached Frocessor. RI does not
appear in the response line in uniFrocessor applications. PG in page wait --the user is not executing because CP is
trying to bring in a page from a paging device. Section 3. CP Commands 83
10 in I/O wait --the user is in I/O wait because access to
the device is not available at the moment. EX in instruction si.ulation wait --the user is waiting for
the completion of instruction PS in PSi wait --the user is in an enabled wait state for
high-speed I/O devices.
DF in attached processor configurations, the processing of a
synchronous (progra. or SVC) interrupt for this user has
been deferred until the system lock is available. DF is
not applicable for uniprocessor operations.
Note: In cases where a virtual .achine may be in aore than one
of-the above states, only one state is displayed; the state
displayed is the first one encountered in the order of priority
indicated above.
sss is a hexadeci.al nu.ber indicating the number of pages resident
in real storage.
ttt is a hexadeci.al nu.ber indicating the nu.ber of pages
esti.ated by the dispatcher as the working set of this user.
Note: The lines of the above response are ordered as follows:
1. Q1 and Q2 users in runlist priority order (dispatching
priority)
2. Bligible list E1 users in scheduling priority order.
3. Eligible list E2 users in scheduling priority order.
The significance of these values is important in
perfor.ance analysis; for details see the 10 USERS IB QUEUE is issued for the QUEUES operand when userid1 xxx userid2 yyy userid1 is a user identification na.e(s).
userid2 xxx indicates the real device address. V8/37.Q syste. .§I§1!!! yyy indicates that two users are waiting for I/O to complete on the
device indicated.
Bote: In the case where a virtual machine may have issued iultiple SIOs, the response indicates the real device address
corresponding to the most recent one issued. BO USERS IN I/O WAIT is issued for the I/O operand, when appropriate.
