       ERRIND      (Integer,  Output)  -  If  the  inquired value 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.

       TXP         (Integer,  Output)  -  Returns the current text path as set by default or by a call to GSTXP.
                   Legal values are:

                   0      Draw successive characters in the string such that character n+l appears to the  right
                          of character n. This is text path "right" and is the default.

                   1      Draw character n+1 to the left of character n.  This is text path "left".

                   2      Draw character n+1 above character n.  This is text path "up".

                   3      Draw character n+1 below character n.  This is text path "down".
