------------------------------------------------------------------------------

 Syntax

        GT_RomDate() --> dRomDate

 Arguments:

      None

 Returns:

      Date stamp of the ROM Bios chip.

 Description:

      GT_RomDate() can be used to retrieve the date stamp of the ROM Bios
      chip of a machine. Most IBM compitable machines have the date of the
      ROM help at a certain location in memory, if you are running your
      application on a non-standard machine the date returned may be empty
      or may be incorrect.

      GT_RomDate() can be used for debugging or could be used to tie your
      application to a certain machine (not forgetting that there can
      be more than one machine with the same date!).

 Examples:

      // Check that the application has not been moved to another
      // machine.

      if GT_RomDate() == GT_SToD("19880115")
         // Allow access to application.
      else
         ? "Error: This appliction has been moved to another machine!"
      endif
