[TRNSYS-users] Question about the Equation tool

[Yun]

Dear users

I have used the Equation tool usually when there was no 
necessity to calculate a Maximum value of data.
Somebody let me know how can I get a Maximum value by using the 
Equation tool, please. 

For some example in my case,
 max(data1, data2, data3) -> error
 max(data1 data2 data3) -> error too.
So, I need an example containing "Max" fuction.

Thank you.
