General Command Format

An SCF command always begins with a keyword identifying the command (such as

START, VOLUME, or TRACE).

If the command applies only to the current SCF session, the keyword is followed

immediately by whatever additional parameters are required to specify the action to be

taken by SCF. For example, the SYSTEM command can be entered as

SYSTEM \newsys, where newsys is the name of the system that is to become the

default system.

If the command applies to an object, it is followed immediately by the object type and

the object name. For example, the following command aborts the LINE object called

$LIN32:

ABORT LINE $LIN32

It is not always necessary to include the object name in a command. You can use the

ASSUME command to make SCF work only on an assumed object or object type:

ASSUME LINE

ABORT $LIN32

This command aborts a subdevice on that line:

ABORT SU $LIN32.#PC

If SCF requires additional information, the object name should be followed by a comma

and the parameters required to further specify the action to be taken. For example, the

following command changes the value of the protocol for a line:

ALTER SU $AM3270.#TERM1, PROTOCOL CRT

SCF commands for the AM3270 and TR3271 subsystems permit the use of the

command parameter SUB. You can use SUB to direct a command at subordinate

objects. For example, you may want to start all the AM3270 objects that are

subordinate to AM3270 lines but that are currently not started. One way to do this is

with the following command:

START LINE $AMA1, SUB ONLY

SCF Online Help

SCF provides online support when you use the HELP command; if the HELP

command alone is entered, SCF responds with a menu that guides you through the

available help options. Select from the options displayed in the menu for the

information you need.

Using this menu-mode help facility, you can obtain general information about basic

SCF components, such as attribute specifications, character strings, commands, file

names, integers, and so on.
