[RM] How to select the largest value to make a condition?

[Clifton]

For example, assuming that the carbon dioxide concentration is 800ppm, 900ppm, and 1000ppm in each of the three rooms, I want to create a condition based on the largest value. What should I do?

Here's an option. Make a variable CarbMax and let's call the concentrations Room1, Room2, and Room3.

Set CarbMax to Room1
IF (Room2 > CarbMax) Set CarbMax = Room2
IF (Room3 > CarbMax) Set CarbMax = Room3

Now CarbMax has the maximum value and you can use it in a conditional statement.
