       ERRIND      (Integer, Output) - If the inquired values cannot be returned  correctly,  a  non-zero  error
                   indicator  is  returned  in  ERRIND, otherwise a zero is returned.  Consult "User's Guide for
                   NCAR GKS-0A Graphics" for a description of the meaning of the error indicators.

       ICLIP       (Integer, Output) - Returns the current value of the clipping indicator as set by default  or
                   by a call to GSCLIP.

       CLRECT      (Real,  Array(4))  -  Four  normalized  device coordinates providing the corner points of the
                   current clipping rectangle in the order XMIN, XMAX, YMIN, YMAX.
