       TRNUM       (Integer,  Input)  -  A  normalization  transformation  number.  The  number   of   available
                   transformations  is  implementation  specific.  In the case of NCAR GKS-0A, two normalization
                   transformations are provided:

                   0      Selects the identity transformation in which both the window  and  viewport  have  the
                          range of 0. to 1. in both coordinate directions. This is the default.

                   1      Selects  a  normalization  transformation  in  which the window and viewport have been
                          defined by calls to GSWN and GSVP.

       GSELNT  (Select  normalization transformation) - selects a predefined or user-defined transformation that
       maps world coordinates to normalized device coordinates.

       When a normalization transformation is selected, all world coordinate  arguments  to  GKS  functions  are
       transformed by it.
