Handling multiple strings in a case structure

[SolPS]

Can someone explain how the case structure in the attached screenshot executes? I normally use enums in my state machines and strings occasionally but I've never tried to send multiple commands via a single case. Sorry, I couldn't attach the code because it was just an online tutorial that I'm trying to read and understand. See attached screenshot.

Thanks in advance.

The outer case matches two different strings for the shown case and the inner case selects one of the two. What's the question, exactly?

[SolPS]

How does the outer case structure handle the two commands? Does the case structure handle either of the commands whenever any of them appears on the case structure input?

Yes, each case can match many different comma delimited choices. (same for enums and numbers). Did you read the help?

Thanks Altenbach.
