SCF Object States

Objects have operational states, such as STOPPED or STARTED. The exact

sequence of states that an object goes through varies from object to object and from

subsystem to subsystem. Some subsystem commands recognize only a few states.

States are described in the

SCF Reference Manual for G-Series RVUs

The operational state of an object at a given instant is important. For example, certain

commands have no effect on objects when those objects are in some states but can

affect objects when they are in another state.

Using SCF

This section describes how to start SCF, how to control its input and output files, and

how to enter SCF commands.

You can start SCF in interactive mode by using the TACL RUN command, or you can

start SCF in noninteractive mode by using a command or OBEY command file (or

TACL macro or routine). The TACL RUN command used to start SCF is described on

the next page. SCF commands are described in the

SCF Reference Manual for G-

Series RVUs

SCF can accept input from a terminal or a disk file. You can change the input source

dynamically by using the SCF OBEY command. These capabilities are described in

further detail later in this section under Input Sources on page 4-12.

SCF can direct output to a disk file, a terminal, or a printer. You can change the output

destination dynamically for a single command, a series of commands, or an entire SCF

session. These capabilities are described in further detail later in this section under

Output Destinations on page 4-13.

Running SCF

SCF resides in the file $SYSTEM.SYSTEM.SCF. To start SCF, you use the TACL RUN

command described in the

TACL Reference Manual

. Only the run options that pertain

to SCF are shown in the following TACL syntax. You namely need to specify SCF run

options because the default values are appropriate for most situations.

The command for running SCF from TACL is as show below.

[ RUN ] [ \remote.]SCF

is the TACL command to run the SCF program on the local system or, optionally,

on the remote system. This command is described in detail in the

SCF Reference

Manual for G-Series RVUs

[ RUN ] [ \remote.]SCF [ /run-option/] [ $process ]
