DOW()


Syntax:     DOW(<expD>)

Purpose:    To convert a date value to a number identifying the day of
            the week.

Argument:   <expD> is a date value to convert.

Returns:    An integer numeric value.

            DOW() returns a number between zero and seven.  The first
            day of the week is one (Sunday) and the last is seven
            (Saturday).  If <expD> is empty, DOW() returns zero.

Usage:      DOW() is useful when you want date calculations on a weekly
            basis.
