Hello, I have created some variable in the mainstream of a Julia stream; in order to pass them (to be modified) inside a for loop, I first declared them as global. For instance; global a = 10 for i in 1:100 b = a*2 a = b*0.1 end give the error: UndefvarError: a is not defined If I define g…

Or, as a puzzle for you: julia> let a = 10 for i in 1:1 b = a*2 a = b*0.1 println(b) println(a) end end 20 2.0 julia> a 10 I admit, the documentation https://docs.julialang.org/en/v1.3-dev/manual/variables-and-scoping/…
