Access local variable outside an if

Question

How to create/modify a variable within a if and be able to access it without having to set it in global mode/scope. I am working on a Lua file similar to this scheme:

    if verificacao then
        local variavelDoArquivo = 123
    end

    -- preciso acessar a variável que foi criada pelo if verificação fora do if mas no mesmo arquivo. Ex:
print(variavelDoArquivo)

Behold functioning on the ideone and in Codingground.

In this situation returned blank on the console, but in some cases returned nil in other situations. How can I create/set a variable within the if and be able to access it externally without having to create a scope?

I don’t know if you’re doing what you want, but it’s the solution. I think initialize the variable already in the statement and only change its value within the if would be better, but it depends on the outcome you expect.

Declare it out of the if and attribute within:

local variavelDoArquivo
if true then
    variavelDoArquivo = 123
end
print(variavelDoArquivo)

I put in the Github for future reference.
