Done and some ... I added extra tests to ensure that not only was the 
code surviving to the end but that the alternate entries are resoponding 
to the correct input.  I also called it altreturn_3.f90 :-)

At the same time I did the int to bool change that you had requested, 
Steve, and corrected the typos noted by Jerry.
