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. It is seldom necessary for you to

specify SCF run options because default values are appropriate for most situations.

The command for running SCF from TACL is:

[ RUN ] [ \remote.]SCF

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

on the remote system. This is discussed further under Running SCF in a Network

on page 1-15.

run-option

is one or more of the following RUN options, separated by a comma:

CPU num

specifies the number of the processor in which SCF is to execute. The

variable num is an integer in the range 0 through 15. If you omit this option,

SCF executes in the same processor as TACL. (However, if you omit the CPU

option and a $CMON process exists, $CMON may specify a processor other

than the one in which the current TACL process is executing. See the

Guardian Programmer's Guide for information about $CMON processes.)

DEFMODE { OFF | ON }

specifies the initial DEFMODE setting and determines which DEFINEs are

propagated to this SCF session. If you do not include this option, the initial

DEFMODE setting for SCF is the DEFMODE setting for the current TACL.

OFF disables DEFINEs for this SCF session. ON enables and propagates all

specified DEFINES to this SCF session. See page 4-20 for more information

on SCF support for DEFINEs.

IN filename

specifies the input file (usually a command file) for the SCF process. This file

name is sent to SCF in its startup message. If you do not include IN

filename, the SCF process uses the IN file in effect for the current TACL

(usually your home terminal). For more information, see Setting the Initial

Input Source and Changing the Input Source on page 4-8.
