Directory Program If privilege class F is assigned to a virtual machine, I/O error recording is not automatically done. This allows
the class F user to set the kind of error recording he wants
to perform.
pri is a number from 1 to 99 used by the control program priority
dispatcher. One is the highest priority and 50 is the
default. The same priority value can be used for several users.
Also, if the specification for this statement is not entered,
then line end (Ie), line delete (ld), character delete (cd),
and escape (es) characters default to system-defined values.

The ACCOUNT control statement defines an account number and a
distribution identification. The distribution identification has no
internal system use; it is provided for customer use (for example, a
code for distribution of printed output). The ACCOUNT statement is
optional. However, if this statement is omitted, both the account
number and the distribution code default to the userid. This statement
(if coded) must follow the USER statement and precede the first device
statement. The format of the ACCOUNT control statement is: r--------·----------------------------------------------------------------------------------------- I Account number (distribution]

Directory Program is a one-to eight-character account number that is punched in
the accounting data for this virtual machine. The USERID from
the USER statement is also punched in the accounting data.
distribution
is a one-to eight-character distribution identification word
that is printed or punched with the userid in the separator
for spooled output for this user. This value is optional and
defaults to the userid from the USER statement if oJllitted.
The OPTION control statement selects specific options available to the
user. This statement is optional and, if used, must follow the USER statement or another OPTION statement, and precede the first device
statement (CONSOLE, "DISK, DEDICATE, LINK, or SPOOL) • Multiple OPTION statements can be inserted if the options selected exceed the statement

during virtual processor run time and also during virtual wait
time. (If the virtual machine does not have the REALTIMER
option, its timer reflects only the virtual processor run time
used.) This option is required for virtual machines running
systems or programs that go into a wait state expecting a
timer interruption. This timing ability can also be obtained
by issuing the CP command line SET TIMER REAL. ECMODE allows the virtual machine to run in extended control mode.
The ECMODE option must be specified for virtual machines using
operating systems that:
1. Operate in System/370 extended control mode (such as VM/370 itself).
2. Use the dynamic address translation facility (such as OS/VS1, OS/VS2, DOS/VS, and VM/370). 3. Use control registers other than zero

The ECMODE option must also be specified for the virtual
machine that is to perform system support or updating, and for
an RSCS virtual machine. ECMODE is also required when using
the clock comparator.
Note: A virtual machine defined without the ECMODE option in

machine with the ECMODE option may address up to 16 I/O Part 2. Defining Your VM/370 System 203
