Running SCF
the completion message indicates an error condition, SCF displays an appropriate
message and then displays its prompt.
Running SCF
SCF resides in the file $SYSTEM.SYSTEM.SCF. To start SCF, use the TACL RUN
command. SCF can be run in either of two modes: interactive or noninteractive. For
more information about the syntax of the RUN command and these two modes of
operation, see the SCF Reference Manual for G-Series RVUs and the SCF Reference
Manual for H-Series RVUs.
Input Sources and Output Destinations
SCF accepts command input from a terminal or a disk file; it directs output to a disk
file, an application process, a terminal, or a printer. The RUN command that initiates
SCF determines the initial input source and output destination.
When an SCF line is active, you can change both the source and the destination
temporarily. For information about how to set the initial input source and output
destination and how to change them, see the SCF Reference Manual for G-Series
RVUs and the SCF Reference Manual for H-Series RVUs.
Online Help
SCF provides online support when you use the HELP command (described fully in the
SCF Reference Manual for G-Series RVUs and the SCF Reference Manual for
H-Series RVUs). If you enter the HELP command, SCF responds with a menu that
guides you through the help options; select from the options displayed in the menu.
