Hi Brian/Cristi/Wannes/Kroeger/Kero, and others,

Yes. I've done what you have all suggested. Thank you.
But I was hoping for something "cleaner". Sorry.

Can we request RCR for this?

I like the private/public clause for methods. I hope we can provide
something like it for vars though; that is, make local vars "public" or
"private" 

like,

#test.rb
#sample script---------------->8

private_var foo	# <--declare something like this or whatever
                  # foo will be visible up to end of test.rb only
                  # as if foo now becomes @foo, or $foo, or what

foo=["a","b","c"]

def mfoo
    foo.each do |f|
        p f
    end
end

# go-go-go!
mfoo
#end sample script------------>8


Will this break ruby design? 
If yes, please forget i asked.

Thanks and kind regards -botp
