RESULTING ARGUMENT: None

FUNCTION          : Clear the current buffer, and read a specified file into
                    it.

                    The file name is taken from the command string, and
                    consists of all characters immediately following the
                    command up to the first ESC or RETURN encountered. If
                    the file name is empty, the default file for the buffer
                    is used. If this is not set, an error is reported. The
                    file name may include a directory specification.

NOTE              : The default file for the buffer is set to the new name.
