response, and event-message buffers. SPI is described in the Distributed Systems
Management (DSM) Programming Manual.
SCF Commands
Several commands are available for displaying and changing SCF session parameters.
Table 4-1 shows these commands and their effects.
Table 4-1. Changing SCF Session Parameters
Other SCF commands operate on the objects (lines, subdevices, processes, and so
forth) belonging to each subsystem. In the Telserv subsystem, for example, the ADD
and DELETE commands add objects to and delete objects from the list of objects
controlled by SCF. Once an object is subject to control by SCF, you can use the
START, STOP, and ABORT commands to change the state of the object, or you can
use the ALTER command to change the values of selected attributes of the object. You
can also use the INFO command to display the current attribute values for objects and
the STATUS command to display the current dynamic status of objects.
Command Effect
ASSUME defines a default object to be used when the object is omitted
from an SCF command.
ENV displays the current settings of the SCF command parameters
that establish the program environment.
HELP displays a list of the available SCF commands. You can also
request additional specific information, such as command syn-
tax, for each command. For most subsystems, you can also
request subsystem-specific information for their commands. The
HELP key is also available, as it is in TACL, to display com-
mand syntax.
OBEY causes commands to read from a a specified command file in
interactive mode.
OUT directs the display output to a specified file (the output file),
while continuing to send display output to the location set at
SCF startup time.
SYSTEM designates the default system name for all file-name and object-
name expansions.
VOLUME designates the default volume and subvolume for expansion of
all file-names.
RUN allows you to run another program during an SCF session.
Note. For a complete description of the commands described in this section, refer to the Sub-
system Control Facility (SCF) Reference Manual. General SCF commands are not described
in this manual.
