       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.

       FONT        (Integer, Output) - Gives the font number as set by default or by a  call  to  GSTXFP.   FONT
                   number one is a simple default ASCII font. Values for FONT between -2 and -20 (inclusive) are
                   Hershey fonts.

       PREC        (Integer, Output) - Gives the text precision as set by default or by a call to GSTXFP.

                   0      String precision (good)

                   1      Character precision (better)

                   2      Stroke precision (best)
