gopks - opens the GKS package

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

       #include <ncarg/gks.h>

       void gopen_gks(const char *err_file, size_t mem_unit);

       ERRFIL      (Input,  Integer)  -  The  Fortran  unit  number  to  which error messages are to be written.
                   Typically this should be unit 6.

       BUFA        (Input, Integer) - The dimension of an internal buffer.  Currently in NCAR  GKS-0A,  BUFA  is
                   ignored.

       CALL GOPKS (ERRFIL, BUFA)

       To  get  output  to  any  workstation,  GOPKS,  GOPWK  and  GACWK must be called in that order.  For jobs
       producing only CGM output, the three calls to GOPKS, GOPWK and GACWK can be replaced with a call  to  the
       SPPS function OPNGKS.
