script local variable can't see

[somefood]

Hello.

I study mikrotik script.
what’s wrong.JPG
I input :local variable and print value but I can’t see value
Am I wrong?
I refer wiki site but my result is not same.

Each line written in terminal is treated as local scope.

Try this in terminal:

:local hello 8 ; :put $hello
8

That will work but not:

:local hello 8
:put $hello

In scripts the local scope is within the curly braces { }

So this wiki example is wrong?

I see some script example, the local variable aren’t in {} scope.
I’m so confused here’s another link

Yeah, both examples are wrong. Can’t use local vars like that.

In winbox, go to “System/Scripts”, you can monitor the global variables from the Enviroment tab. Very handy when learning or debugging. Even the variables that you declare in the CLI will appear here.
