It should do nothing if it was anything but what's up there, but I put
in a default just to see if it would fix it (it didn't).  What's strange
is that it worked fine when I only had case 2 but no case 3.  This is
just something I'm using to test get familiar with Allegro, as I'm just
starting to use it, and it's ironic that a hidden syntax problem is
holding me back.
