* A little explanation is required here. The system service routine
* $CRELNM creates a new logical name and assigns it a value and
* miscellaneous properties. Among the properties is the access mode,
* which specifies whether the logical name has USER, SUPERVISOR,
* EXECUTIVE, or KERNEL mode. Unfortunately, it cannot define a
* logical name with an access mode higher than that of the process
* it is running in, and for USER mode processes this means that the
* logical name can only be defined with USER mode. This, in turn,
* means that the logical name will vanish when the image exits. To
* cirumvent this, we may use the RTL routine LIB$SET_LOGICAL, which
* requests the shell under which the process is running to define
* the logical name for it at SUPERVISOR access mode, which survives
* the exit of the current image.
