Button question.

Hi.

I am new on programming, and i wnat to programm a row of 16 leds flashing, but with different flashing patterns, i expect to control the flashing patter trough a momentary switch and i was thinking if anyone could help me with this because i cannot figure out how to insert the momentary switch in the middle of the flashing patern so it can "read" the input port.

So the question will be: How to read a port in the middle of a process.

Thanks
