Hi all, I have a function name in string variable, and I would like to call this function. How do I do this?

Like this:

function A()
-- code here
end
 
function B()
-- some other code here
end
 
if itsasunnyday then
x = A
else
x = B
end
 
-- here I would like to call the x function

I read that page before, but I didn't get the use of _G, and where to use it. Thanks again!
