Alternating display values

[jsclownfish]

I had some time today and I was thinking about how to get more info out of the space on my main display. So, I thought I might be able to switch between temperature monitors or maybe have them scroll in the same area on the screen. I remember being advised against using the delay function and that seems to make sense as the temp monitors don't update when things are in a delay. I tried two things: one was scrolling the three temp values across the screen (that didn't work so well), and the second was to switch between temp probes. I am using the Modulo function and the second clock to determine when to switch (or move in the case of scrolling). Is there a better way to do this or is this a bad idea I am not foreseeing?

Here is the demo code I am using....

Modulo should work fine. I don't foresee there to be any problems with using it.
