I spoke to my FAE from Microchip today.  He suggested that I use the 16F873
instead of the 16C773.  I told him that according to the web site, the F873
only has 3 I/O's.  Well, it turns out that this is a big mistake.
Unfortunately, that error is also in the table of PIC microcontrollers that
I uploaded last week.  I'm sorry for this error...I got burned by it
myself...
