+** Purpose:
+** Check the length of a number of arrays.  The first is a normal string
+** which should return its length.  The second has two bytes and a null 
+** character, which only returns a size of 2, and the last is just a NULL
+** array which should return 0.

+ *  as it may, I haven't seen a way to get it to behave otherwise
