Hi Rob, Thanks for your suggestion. I had seen that method of changing the value of some panel's control before, but it hadn't occured to me to use in that manner. I thnk that's actually a pretty clever, and could be quite useful.
Unfortunately, this method wouldn't really work the way I want. My task is an iterative one, being run in a while loop. Between iterations of the loop, there is a set delay time. In certain situations, this can be quite substantial. I was attracted to using notifiers because of the "Wait on Notification" function. This would allow me to track the amount of time spent waiting, but I could break out of the wait period instantly when I received a command. If I used the "Wait" function and specified a certain length of time, I can do nothing until that time has elapsed. So if the delay is 10 seconds, my VI won't terminate for 10 seconds. I could break the wait down into several sections to reduce the time between sending the command and receiving it, but this would amount to polling a variable and I don't want to do that. In any case, sincere thanks for your suggestion. Victrick
