This class adds only one resource to the Workstation set of resources. This resource enables the user to specify a full Unix path name for the output metafile.
An important thing to remember is that only one NcgmWorkstation object can be created at a time. Therefore, you must destroy the current instance of the NcgmWorkstation object before creating a new one. You can use the NhlDestroy function for this purpose.
Another thing to remember with the NcgmWorkstation object, is that the metafile is written using FORTRAN I/O. This means that the NcgmWorkstation object uses one of the available UNIT numbers. The NcgmWorkstation starts with UNIT 7, and increments until it finds a UNIT number that is not currently in use.
