Devices (Job)

Draft MDC Standard

Right Hand Pointer

7.1.3.5.3 Characteristic: Devices

^$Job( processid , expr V "$Principal" ) = devicexpr (principal device)
^$Job( processid , expr V "$IO" ) = devicexpr (current device)
^$Job( processid , expr V "Open" , devicexpr ) = (for each Opened device)

These nodes specify the device information associated with process processid. The value of node "$Principal" is equal to the value of $Principal for that process. The value of node "$IO" is equal to the value of $IO (current device being used) for that process. The devicexpr nodes beneath "Open" are the device identifiers for all the devices which are currently Opened for that process.
