Generate a Worst Case (max) Channel from 2 or more channels

Hi,

I'm creating a script to process a range of data channels, what is the easiest way to combine two channels (or more) in a way that the maximuim values are preserved in the result channel

eg

Channel 1     Channel 2      Results Channel

1                          5                       5

2                          6                       6

3                          1                       3

4                          2                       4

5                          5                       5

I'm currently using DIAdem 2019 64bit
