       CLSGKS is somewhat dated.  It was primarily used with NCAR GKS-0A when this package only allowed for a
       single metacode workstation.  Now that the NCAR GKS package provides for multiple workstations to be
       open, it is recommended that standard GKS calls to GDAWK, GCLWK, and GCLKS be used instead.
