I think there is something wrong in the programmer. Nothing that I write in PBPRO seems to work. In fact, the ONLY thing I have gotten to run is the .hex X-1 board test file that came with the development board. The interesting thing is that this file is loaded directly into the programmer and never passes through PBPRO.

I looked at the configurations of the compiler. PBPRO came with Mecanique microcode and that is the IDE I'm using. It also came with MPLAB so I played with it a bit. According to the info that came with the compiler, for the 16F series, the IDE automatically uses MPASMWIN - so I looked at that. It is creating a hex file, so I took the hex file and passed it to the melabs USB programmer and then programmed the chip - I even used the manual clear on the programmer and then checked the memory in the chip after programming to be sure that the same hex file was present in the chip as that created by MPASM. I also switched off MPASM and opted to use the PM assembler provided - no luck. I even wrote the a simple led on/off program in assembly using the ASM...ENDASM commands in PBPRO and that didn't work. The bottom line is that nothing I do in PBPRO works. The problem is likely so fundamental that "we" are all overlooking it. Yes, the board is plugged in and I have measured the Vdd (4.99V).
