^$DEVICE

Draft MDC Standard

7.1.3.2 ^$Device

^$D[EVICE] ( devicexpr )

    devicexpr::= expr V device
    device::= devicespecifier; an implementation-specific device identifier

^$Device provides information about the existence, operational characteristics and availability of devices.

Note: The holding of information about a device when it is not open may be transitory. There are also likely to be more devices in a system which could be opened by a M[UMPS] process than will have information stored in ^$Device.

Device characteristic information for a device is stored beneath the ^$Device(devicexpr) node:
