Installation guide

source input-file
This command allows you to source input from an external command
file. If any errors occur during command parsing or execution, the
command file is closed at that point. The default file name extension
.scu is appended to the name of the input file if no extension is
supplied. If the scu utility cannot find a file with the .scu extension,
it attempts to locate the original input file.
switch [
device-name ]
This command accesses a new device or a previous device. If no device
name is specified, the command acts as a toggle and simply switches
to the previous device, if one exists. If a device is specified, it is
validated and becomes the active device.
