Yes sorry, I phrased this wrongly, I had intended to only talk about the 
use of Hollerith constants.  But this is moot because due to what both 
Jakub and you rightfully pointed out, LOGICAL will likely have to seize 
being a BOOLEAN_TYPE.  Which in turn will restore the traditional 
Hollerith behavior.  If all goes well.
