	PLEASE NOTE: this program demonstrates "COME FROM" for program control.
        This is the normal "COME FROM", with labels as targets; refer to
        come-from-gerund.gi for an example of using gerunds as targets,
        and to come-from-computed-label.li for an example with computed labels.

        that the program says: III
