Controlling System Activity
Use Nonshareable Devices (ND)
This capability allows the use of devices other than terminals and discs
including spooled devices. If the device is not spooled, the user has
complete control of it. Examples of nonshareable devices are card
readers, line printers, magnetic tape units, and plotters. This
capability is not needed to use the standard job or session input and
list devices.
