LEN()


Syntax:     LEN(<expC>/<array>)

Purpose:    To return the length of a character expression or the
            DECLAREd number of elements in an array.

Arguments:  <expC> is the character string to determine the length
            of.

            <array> is the array to count.

Returns:    An integer numeric value.

            If the character expression evaluates to a null string,
            LEN() returns zero.

Library:    CLIPPER.LIB
