HOLD Use the HOLD command to place user spool files in a system hold status.
The spooling operator has the ability to hold the files of any user of
the system.
The system hold status for a user is remembered even if the user is
not currently logged on. Both the user's files and his hold status can
be reset with the FREE command.
Files held by a class D user can only be freed by a class D operator.
A spool file can be held by a user or by the system spooling operator. A spool file held by a spooling operator or a user can only be freed by the same spooling operator or user. A spool file can be in a double hold
status and can be processed only if both holds (system and user) are reaoved. The format of the BOLD command is: HOld userid PRINTER PRT PUNCH PCB ALL
None.

Section 3. CP Commands 79

INDICATE E Use the INDICATE command to display, at the console, the use of and
contention for the major system resources of processor and storage. The
users of this command include the general user and the system analyst.
The general user can display the use of and contention for the major system resources of processor and storage. He can also display the number of I/O requests his virtual machine has made and the total amount
of resources he has used during his terminal session. If he uses the
INDICATE command before and after the execution of a program, the
command indicates the execution characteristics of that program in terms
of resource usage.
The system analyst can identify the users in queue1 and queue2, the I/O devices they are queued up on, the paging devices that may have been
filled, or the execution characteristics of any user and the total amount of resources used by him. The system analyst can use the data on system resource use and
contention to monitor the performance of his system. He can thus be
aware of heavy load conditions or low performance situations that may require the use of more sophisticated data collection, reduction, and
analysis techniques to resolve these conditions. The format of the

users being serviced. USER [ * ]
[userid]
allows a system analyst to find out more about the resources
used and occupied by his virtual machine, and events that have
taken place. USERID allows the system analyst to determine the
activity of virtual machines in terms of the resources used and
occupied and events that have taken place. Class E users can
access data from the VHBLOK of any user currently logged on to
the system in their attempts to understand an overload or poor
performance situation. The output of this operand is the same 80 V!/370 Operator's Guide
