CHARRELA()

Syntax:     CHARRELA(<expC1>,<expC2>,<expC3>,<expC4>)

Arguments:  <expC1> denotes the character to search for in <expC2>.
            <expC2> is the string to search for character <expC1>.
            <expC3> denotes the character to search for in <expC4>.
            <expC4> is the string to search for character <expC3>.

Returns:    A numeric value.
            The position in which both <expC1> and  <expC3> occur in
            the corresponding strings.

Usage:      The function will form a relationship between two strings.  It
            will determine the position where both the <expC1> character
            in the <expC2> string and the character <expC3> in the
            <expC4> string appears.

Notes:      The function will return the value 0 if it was not possible to
            find a relationship.

Library:    CT1.LIB
