General SCF Command Format
•
ALL specifies that the named object and the subordinate objects are affected.
•
NONE specifies that the named object is affected but none of the subordinate
objects are affected.
For more information about subdevices, refer to Effect of the ASSUME Command on
Subdevice Specification on page 5-6.
General SCF Command Format
An SCF command always begins with a keyword identifying the command (such as
START, VOLUME, or TRACE). The keyword is followed by the object type and the
object name. Specific information about the format of each SCF command appears in
Section 5, SCF Commands, and in a separate manual for each subsystem, as listed on
page xii.
Commands Without an Object Type or Object Name
If the command pertains only to the current SCF session, the object type is null and
the keyword is followed immediately by whatever additional parameters are required to
specify the action to be taken by SCF. For example, you can enter the SYSTEM
command as SYSTEM \ newsys , where newsys is the name of the system that is to
become the default system.
Commands With an Object Type and Object Name
If the command pertains to an object, it is followed immediately by the object type and
the object name. For example, this command aborts the LINE object called $LIN32:
-> ABORT LINE $LIN32
This command aborts a subdevice on that line:
-> ABORT SU $LIN32.#PC
If additional information is required, you enter a comma after the object name and
specify the parameters for further action to be taken. For example, this command
changes the value of the LINEBUFFERSIZE attribute for a line:
-> ALTER LINE $LIN32, LINEBUFFERSIZE 12000
When typing several commands using the same object type and object name, you can
use the ASSUME command (described on page 5-36) to reduce keystrokes.
Note. For some subsystems and for some commands, the object type is optional. For
example, the STATUS $DATA01 command implies the DISK subsystem.
