Value: This property specifies the Value of a Boolean value derived from the source token as follows.

If the source token is a PtgBool, the Value is equal to the source token Value. If the source token is a PtgString that contains a formula that evaluates to FALSE or zero, the Value is FALSE; if the source token is a PtgString that contains a formula that evaluates to TRUE or a value other than zero, the Value is TRUE.
