VAL()


Syntax:     VAL(<expC>)

Purpose:    To convert numbers contained in a character expression to a
            numeric value.

Argument:   <expC> is a character expression to convert.

Returns:    A numeric value.

            VAL() stops evaluating a character expression when a second
            decimal point, the first non-numeric character, or the end
            of the expression is reached.

Usage:      VAL() is useful when you want to do calculations using
            numbers contained in a character expression.

Library:    CLIPPER.LIB
