Setting the Initial Input Source
•
Noninteractive input usually appears in the form of a command (Obey) file.
Command (Obey) files are usually EDIT files that contain a series of commands.
For more information about interactive and noninteractive modes of operation, see the
Subsystem Control Facility (SCF) Reference Manual.
Setting the Initial Input Source
To specify an initial input source for an SCF session, use the IN option of the RUN
command. You can specify a terminal (identified by its logical-device name) or a disk
file. For example, the following TACL RUN command initiates SCF and directs it to
read commands from a disk file named $DATA.SCF.STARTUP:
19> SCF / IN $DATA.SCF.STARTUP /
If you run SCF from TACL without specifying an input file, SCF reads its input from
your terminal.
Output Destinations
SCF can direct output to a disk file, an application process, a terminal, or a printer. The
initial output destination is determined by the form of the RUN command used to initiate
SCF. The output destination can be changed dynamically during an SCF session.
Setting the Initial Output Destination
To specify an initial output destination for an SCF session, use the OUT option of the
RUN command. You can specify a terminal (identified by its logical-device name), a
disk file, an application process, or a printer. For example, the following RUN
command initiates SCF and directs it to send its output to a disk file named
$DATA.SCF.DISPLAY:
20> SCF / OUT $DATA.SCF.DISPLAY /
If you run SCF without specifying an output file, SCF sends its output to your terminal.
SCF Online Help
SCF provides online support when you use the HELP command described in the
Subsystem Control Facility (SCF) Reference Manual. 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 SCF basic
components, such as attribute specifications, character strings, commands, file names,
integers, and so forth.
In addition to getting general SCF information, you can obtain information specific to
your particular subsystem.
Note. The online help facility is interactive; it cannot be invoked from a command (Obey) file.
