GQCHUP (Inquire character up vector) - retrieves the current value of the character up vector.

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

       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.

       CHUX        (Real, Output) - Gives the X world coordinate of a the up vector.

       CHUY        (Real, Output) - Gives the Y world coordinate of a the up vector.

       CALL GQCHUP (ERRIND, CHUX, CHUY)

       The up vector is that vector formed by the two coordinate points (0.,0.) and (CHUX,CHUY).  See GSCHUP for
       more details on the meaning of the character up vector.
