            [SIC\]DIFF Var1|File1 Var2|File2

        List  the  differences between two entities. Each entity can be either a
        Sic variable name or a GDF file name  (images,  cubes,  UV  tables,...).
        Comparison is made on their headers (if both variables provide a header)
        and/or their data (if both variables provide a data array).

        The result of the last comparison (true/false) is saved in  the  logical
        variable SIC%DIFF.
