GSTXCI (Set text color index) - sets the text color index.

       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.

       #include <ncarg/gks.h>

       void gset_text_colr_ind(Gint text_colr_ind);

       CALL GSTXCI (COLI)

       All  text  strings  drawn  with calls to the GTX output primitive will be drawn with the color associated
       with index COLI until GSTXCI is called again and a new index is assigned.

       For all GKS output primitives, color is assigned using a color index. The color indices  run  from  0  to
       255,  where  0  is  the  background  color  index  and 1 is the foreground color index.  Color values are
       associated with indices by calls to the GKS routine GSCR.  If a color index is used  that  has  no  user-
       assigned  color  value  set  in a GSCR call, then a device-dependent color value will be assigned to that
       index.
