Description

PRQLC prompts you for input using the locator-class logical input device specified by the device number and the workstation identifier.  If the input status is POK, this function returns the world coordinate point and view index of the view transformation Digital PHIGS uses to translate the normalized projection coordinate points to the world coordinate points.  See Getting Started with DEC PHIGS for more information about view indexes. 

Digital PHIGS uses the current workstation transformation to translate the device coordinate point to a normalized projection coordinate point. 

This function ignores the z-coordinate components and returns a two-dimensional result.
