 The general forms of the device display command are:

	DEVices dd:
	DEVices /LOG

 Where dd: is null or a two letter device type.  If it is null,
 information on all devices is displayed.  If it is non-null,
 information is displayed only for all units of device type dd.

 If the DEV /LOG form is used, a list of all logged-on terminals and
 their login UICs is displayed.
