"UndefVarError: V not defined" using simple loop

I recommend working within the REPL where you have global softscope.

julia> V=1
       for i in 1:2
       print(V)
       V=2
       end
12

Outside of the REPL, you need to declare V as a global within the for loop. Alternatively and preferably, execute this within a function.
