Basic Input from the Command Line in Rebol

Question

I am currently in the process of learning Rebol.

In other languages I know, I can read input from the command line, for example in Java:

Scanner sc = new Scanner(System.in)
sc.nextLine();

In C#

Console.ReadLine();

In C

scanf("%s", s);

I was wondering how one would accomplish the same thing in Rebol.

Answer 1

You can use the input command to ask for input at the console.

>> name: input
Joe
== "Joe"

Answer 2

The ask function complements input by printing a string prior to requesting input:

age: ask "How old are you? "

It also has a /hide refinement to conceal input:

pass: ask/hide "Enter your password: "

At this time, /hide is not implemented in Rebol 3 alphas

A longer answer (and for intermediate-level at least) would include monitoring the system/ports/input port (you can do source input for how this is done for you)—this can be used in cases where input doesn't originate at the console (such as shell, CGI).
