This is the Edit > Correct Indentation feature, which automatically indents the current selection. The Edit menu provides a very interesting feature, commonly known as a ”pretty printer” in most languages.
We can also select a few lines in the script, right click (or Cmd+Click under Mac), and get the context menu which is presented in figure 6. The results which are produced in the console are only those which are associated with printing functions, such as disp for example. Execute File Into Scilab executes the file, as if we used the exec function.Evaluate Selection executes the statements which are currently selected.This implies that the statements which do not end with the semicolon ” ”character will produce an output in the console. Load into Scilab executes the statements in the current file, as if we did a copy and paste.The most commonly used features are under the Execute menu. There are many features which are worth mentioning in this editor. This editor manages several files at the same time, as presented in figure 5, where we edit five files at the same time. The editor can be accessed from the menu of the console, under the Applications > Editor menu, or from the console, as presented in the following session. Figure 5 presents the editor during the editing of the previous ”Hello World!” example. Scilab provides an editor for editing scripts easily. The auto-completion works with functions, variables, files and graphic handles and makes the development of scripts easier and faster. We can then use the up and down arrow keys to select the function we want. Scilab displays a listbox, where items correspond to all functions which begin with the letters ”disp”. Then we can type on the key, which makes a list appear in the console, as presented in figure 4. In the following session, we type the statement disp in the console. The key provides a very convenient completion feature. This lets us browse the previous commands by using the up ↑ and down ↓ arrow keys. In order to get access to previously executed commands, we use the up arrow ↑ key.
We can use the left ← and right → arrows in order to move the cursor on the line and use the and keys in order to fix errors in the text. When we edit a command, we can use the keyboard, as with a regular editor. Then we type disp(s) and Scilab answer is Hello World!. We only type the statement s=”Hello World!” with our keyboard and then hit the key. In the previous session, we did not type the characters ”–>”which is the prompt, and which is managed by Scilab.
In the following example, the function disp is used in the interactive mode to print out the string ”Hello World!”. This is indeed a good way of understanding the behavior of the program and, most of the time, it is a quick and smooth way of performing the desired computation. The goal is that the reader can experiment with Scilab behavior by himself. This document is designed so that the Scilab examples which are printed here can be copied into the console. The first way is to use Scilab interactively, by typing commands in the console, analyzing the results and continuing this process until the final result is computed. Finally, we present two major features of Scilab: the localization of Scilab, which provides messages and help pages in the language of the user, and the ATOMS system, a packaging system for external modules.

We also present the management of the graphical windows with the docking system.
