Have you tried a simple assignment?

value="off"
other_value = value == "on" ? "YES" : "NO"
puts other_value
=> "NO"

When in doubt, fire up irb and just try something. You'll probably
figure out the answer you were looking for in less time than it takes
to write an email and wait for a response, and I guarantee that you
will learn more in the process.

I've been doing Ruby for more than 9 years, and I still have an irb
session running most of the time. It is an invaluable tool.

do you really need the "YES" and "NO"?
Why not just assign the other_value to true or false?

i.e. other_value = (value=="on")

Then you are dealing with booleans which are less prone to error imho.

Thanks for all of the comments. Yes Bool is a potential (although the
orig mail was with simplified test data). My irb wasn't too far away,
but I just got into the ternary operation and thought, hmm I'm not sure
how to do that!
