Subject: [newbie] make local var visible

Hi All,

I may not be feeling well today, so pardon me pls.

I am modifying/cleaning many scripts here (most of them just a page long,
two at most, and most of them coming fr perl/bash origin).

I encountered a wall though.

Consider,

>cat test.rb

#sample script---------------->8
foo=["a","b","c"]

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

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

i just enclosed the some commands with def mfoo / end to make a new method
mfoo and make my script cleaner, and besides, i may be calling mfoo again.

running the above, i get:

>test.rb

>test.rb:4:in `mfoo': undefined local variable or method `foo'
        from test.rb:9


So how can i force foo visible to mfoo()?

Thanks in advance.
