First of all, thanks for the input.  I just realized something as the result of the "look at the register" comment.  The program is set up for the falling edge interrupt trigger, but the way the RB is configued, pressing the RB.0 button on the I/O panel takes RB.0 from 0 to 1.  After I release the botton, the interrupt is generated.
 

If i quickly click it again, it gives the correct response of a 1 result, else if I do not "re-click" RB.0 is give the 0 response.

 

I wil have pull-up resisters on the RB.0 line, so for a single interrupt source that should work.  If I include "  PLP_B = %11111110" or the inverted, I do not get a level 1 in RB.0.  Is ther any way of actually setting RB.0 high and then having the I/O panel take it low?

 

I will get into the more complicated stuff later, but I am still having fun......
