You have to iterate through all the Components, then get a reference to
each Panel Component, then get the Label from the Panel's 1st Component.
 Then you get access to the Label's getText() and setText() methods.  I
have written a method, replaceUnitString(), that does this.

Thanks again for your suggestions,
