how to jump out of a continuously running process?

[tarheel1]

I have an application that reads a digital volt meter that I want to work in 2 modes. In one mode, I want it to continuously read the DVM and display the voltage on screen. In the other mode, I want the application to only read the DVM when I press a button. I don't see how to switch from the continuously running section to the single read section since there is no way to effect anything outside of the continuously running procedure

Thanks in advance for your help!
