Description

PQDVL queries the workstation description table and returns values for the following:

•Default initial value

•List of available prompt and echo types

•Default echo area in device coordinates

•Default valuator data record

See Chapter 9 for information on building data records for initializing input devices.  DATREC corresponds to the data record for PET 1.
