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.
