Before using VizPaint2D, you may want to set environment variables. You use environment variables to:
You set and unset environment variables using the UNIX commands, setenv and unsetenv. You can specify environment variables individually before each VizPaint2D session, or you can place them in your .cshrc or .login file so that they are automatically set when you log in to your system.
To see your environment variable settings, use the UNIX command, printenv.
