        Ok, here it comes...

--code begins here --------- actually it begins at the next line ----

        include get.e           -- for value ()

        function get_hex_value ( sequence hex_string )
        sequence ret
                ret = value ("#" & hex_string)
                if ret[1] = GET_SUCCES then
                        return ret[2]
                else
                        puts(1,"BAD HEX VALUE !!\n\n")
                        abort(1)
                end if
        end function
------------------------------ code ended line above -------

        Just include the above in your program and all get_hex_value() to
get the heximal value. Exemple:

         ? get_hex_value("FF")

        Will write 255 to the screen...

        Your welcome...
