You need to read that article again:

http://www.dfanning.com/tips/access_main_vars.html

Here is code (written with proper naming convention, BTW) that
works:

pro example
(scope_varfetch('haha', /enter, level=-1)) = 'Hello'
end

pro example2
example
print, haha
end

And then,

IDL> example2
Hello

Cheers,

David
