I don’t understand what you are asking here.

Also, are you sure that you are programming Julia? The above is not valid syntax.

Are you looking for something like

```julia
 x=parse(Float64,readline(stdin)) 

```

I interpreted your question initially as “how can I pass command line arguments to a Julia script?” (for which you can look at [ArgParse.jl](https://github.com/carlobaldassi/ArgParse.jl)). But now I’m not so sure whether it is the question.
