SYNTAX            : :N

RESULTING ARGUMENT: The number of files for which editing is not completed.

FUNCTION          : Return the number of files specified on the command-line
                    on invokation of TV for which editing has not yet been
                    concluded.

                    This command may be used to determine (in a macro, most
                    likely) whether a buffer-termination command would also
                    terminate the TV session. If the resulting argument from
                    this command is 1, it would.

NOTE              : If TV was called with one file-argument, this command
                    will always return 1.
