	The general format of the Deallocate device command is:

	DEA[LLOCATE] [ddnn:]

	The DEALLOCATE command releases a private (allocated) device where
	ddnn: is the device and unit number.  Privileged users can deallocate 
	any device but non privileged users can only deallocate devices which
	they have allocated.  If no device is specified, the command will
	deallocate all of the user's allocated devices.
