       WKID        (Integer, Input) - A number identifying the workstation to be updated.  WKID must be the same
                   as that used in some previous GOPWK call.

       REGFL       (Integer, Input) - A flag to specify if the  current  picture  should  be  regenerated.   The
                   possible  values  for  this  are  "0" for postpone, and "1" for perform.  For the workstation
                   types supported in NCAR GKS, this flag should always be set to "0".

       CALL GUWK(WKID,REGFL)

       A call to GUWK flushes all GKS buffers to bring the workstation up to date.  GUWK does not flush any NCAR
       Graphics buffers that sit above GKS such as the pen-move buffer in SPPS (see the man page for plotif).
