RE: local and global

["Tai Meng" <tmeng@...>]

So, let me see if I understand your question. I think you are trying to do something as follows:

do
  local x = 1
  function foo()
    local x = 2
    -- now, you want to access the external local variable, x
  end
end

So, perhaps you can try:

do
  local x = 1
  function foo()
    local x_up = x
    local x = 2
    -- now, you can access the x above the function through x_up
  end
end

And just curious, why do you need to write code like this?

Hello,

    No, what I want is to access x in [level-1], this is the x global to the
block/scope. Example:
    --x = 123 -- _G.x
    function test()
            local x = 123 --< I want to access this
            for i = 0,10 do
                local x = x + i --< [local x] = 246 + i
                if x == 130 then
                    [global x ] = x --< [x this level-1] = [local x]
                end
    end

                        Thanx,

                                                                Leandro.
