* Description: This example demonstrates how to select and
* change the workstation device for drawing your
* output to an NCGM file or an X workstation
* window using the following steps.
*
* 1. Create output workstation objects.
* 2. Create the data for the plots.
* 3. Create the contour object.
* 4. Draw the contour object.
* 5. Call frame.
* 6. Change workstations.
* 7. Draw the contour object.
* 8. Call frame.
* 9. Clean up memory.
