12F683 Hangs up?

[nmeyer]

Can anyone see what i am doing incorrectly on this program? When i program the chip, it does nothing. The first thing it should do is turn an output pin on then off. It does not doe this. It is almost like the program never starts. I think i am missing something in the set up. And yes, i have confirmed that my circuit is working by loading a different program into the chip.

Er. MCLR....
You have the MCLR pin defined as 'time_in'. What is connected to this?.

It is pulled to Vdd through a 10K. Nothing else.

Yes, I just caught and fixed that. It works now.
