 Arguments:

      <ncDrive> is an optional parameter that is the id of the drive
      to be read. This paramater can be either a character value who's
      first character is taken as the drive letter or a numeric value
      where 0 = Default, 1 = A:, 2 = B:, etc... If no parameter is
      passed the default drive is used.

      return value will be -1.

 Description:

      GT_Cluster() can be used to find the number of clusters on a
      disk.

 Examples:

      // Each of the following print the number of clusters found on
      // drive C:

      ? GT_Cluster("C:")
      ? GT_Cluster("C")
      ? GT_Cluster("Clipper")         // First letter is used only.
      ? GT_Cluster(3)

      // The next two print the number of clusters on the current drive.

      ? GT_Cluster(0)
      ? GT_Cluster()
