OPNGKS 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 GOPKS, GOPWK, and GACWK be used instead.
Use the ncargex command to see the following relevant examples: agex01.
To use OPNGKS or c_opngks, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
Online: spps, gopks, gopwk, gacwk, clsgks, setusv, getusv, ncarg_cbind
