Description

PQEGD3 queries the workstation description table and returns the Nth element of the list of GDPs that are supported by Digital PHIGS. 

If the GDP identifier is a positive integer, the GDP is registered with the PHIGS standards organization and is portable across PHIGS implementations that support that specific GDP.  If the GDP identifier is a negative integer, the GDP is Digital PHIGS specific. 

Digital PHIGS Version 3.1 does not support this function.
