/DESTINATION=device-name:[directory-name]
Specifies the top-level directory where the utility will install
software product files. If you omit the device name, the utility
uses your current default device. If you omit the directory name,
the utility uses [VMS$COMMON] as the default directory.
If you do not use this qualifier to specify a destination, the
utility installs the software in the location defined by logical
name PCSI$DESTINATION. If this logical name is not defined, the
utility installs the software in SYS$SYSDEVICE:[VMS$COMMON], the
default top-level directory for software product files.
