need to blink

[henery8]

I can't get started with a 16F628. The blink model is for external crystal and I want to use internal OSC and /MCLR - nothing extra. We need to start but this fat monarch is stuck.

If you plan to blink on PORTA, read datasheet section 9 to know how to disable analog comparator.

Thanks Steve
It was a good lead and I've been trying to understand the configuration word from the pic manual. And I tried varous options but nothing actually flashed. I know my hardware is ok because I used another pic made with something else on it. My problem is that configuration word stuff seems quite advanced. As a beginner I don't know enough about pics to know what I need to set. It's simply lack of understanding. Chicken and egg ? Yes.

This is my best guesswork but not good enough
