Hello all,

Thanks to all those who responded both on and off list.

The original code was fine -- it was a bug in the Studio 4.11's 
simulator.  I downloaded and installed service pack 3 for studio 4.11 
and the problem went away.   (Release notes for SP3 don't even mention 
this fix.)

About makes this newbie want to go back to PICs.  At least I've never 
had an issue with MPLAB's simulator...
