OPEN Command
OPEN Command
The OPEN command allows you to select the Subsystem Control Point (SCP) process
with which SCF is to communicate. SCF can communicate with an object only if SCF
can open an SCP process on the system where the object resides.
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file. The variable file-spec is defined on page 5-9.
\system
is the name of the system on which the specified SCP process resides. If omitted,
the default system name is used.
$process
is the name of the SCP process with which SCF is to communicate. If omitted, the
default SCP process ($ZNET) is selected. The variable $process is defined on
page 4-4.
Considerations
•
The OPEN command is needed only if an SCP process other than the default SCP
process is desired; most users never need to use this command.
•
The SCP process must be started before it can be opened. You can start an SCP
process from within SCF by using the RUN command. See page 5-101 for more
information about the RUN command. See also the SCF Reference Manual for
SCP for more information about SCP.
•
SCF can communicate with only one SCP process per system at a time. If you do
not specify an SCP process (either in the command to run SCF or in an SCF
OPEN command), SCF attempts to communicate with the process $ZNET. If this
fails, a warning message is displayed and SCF issues an operating-system
process-creation procedure for the file $SYSTEM.SYSnn.SCP or
$SYSTEM.SYSTEM.SCP, depending on which of the two locations was selected
by the system manager. If this fails, an error message is displayed.
