How do I code an interrupt to act upon simultanious inputs?

[Archangel]

Hi Melanie,
Ya . . . actually I wasn't really in the planning stage yet, the psudo code posted was to give clarity to what I was attempting to do. As I understand it a pic cannot look at 2 simultanious inputs and make a descision based on that information. What I have tenitively decided to do is use a 7442 bcd decoder as switch decoder and buffer and use 1 pin of the pic as an interrupt input to clear the variables of all my for next counter loops(whichever one is running) if that will work. I am still too inexperienced in programming to know without trying if it will. I figure that's what breadboards are for. So I think my real question is, can a counter loop be decremented faster by code from outside the loop or by an interrupt driven event?

Thank You again,
JS

Can you expand and give us the bigger picture.

What are you counting, how many counters, how fast is this count?

Are these push-buttons?

Are you timing how fast a button is being pushed?

What are you trying to achieve?

Knowing a few more details would aid in giving advice.
