23.4.5 Explaining How to Write Program Using Example
Here, we will explain the usage briefly with examples.
23.4.5.1 Moving [Cat] Sprite
The first time Scratch starts, there will be a “cat” in empty Stage. The “cat” is one of Sprites available in Scratch, [Cat] Sprite.
23.4.4 Basics of Using Program
23.4.4.1 Concept of Sprite
If a Sprite is defined in Sprite Area, it appears in Stage Area above it and performs various actions. It is like the main character or actor performing on the stage.
23.4.3 Scratch Overview
When the program starts, the following screen appears. This screen is the main screen where you can create and test a necessary program.

Figure 23‑6 Scratch overview
The screen consists of several main areas. Let’s look at each one.
23.4.2 Starting Program
You can start Scratch from desktop or Applications Menu as follows.

■ Executing Sctarch program in remote connection environment
Note that there is a case where it does not work normally on remote connection. I have searched the Internet for several sources, but the reason for this is still not clear.
23.4 Scratch Language
23.4.1 Features
Scratch is a tool that allows you to create a program in drag-and-drop manner using a visual tool without writing complicated program source code. You can develop animation, interactive art works, game, and so on. While working with Scratch, you do not actually write program code, but you can learn important fundamentals and techniques of programming. It is therefore the best tool for those who are new to programming to understand the concepts of programming and to do various exercises
23.3.3 How to Use Sonic Pi
23.3.3.1 Step 1 – First Sounds with Sonic Pi
First, select [Workspace 1] and enter the following. Then click [Run] button. What happens one day? Then you will hear a beep sound.
23.3.2 Getting Started
You can start Sonic Pi from the desktop or Applications Menu as shown below.
When the program starts, the following screen appears.
23.3 Sonic Pi
23.3.1 Features
Sonic Pi is a sound processing computer program. It is originally developed to support computer and music lessons at school, and it is a live coding synth that everyone can use for free. By making code with this, you can create and play classic and contemporary music styles, from Canons to Dubstep. Even if you want to make funky music like Daft Punk or Will.I.Am, but you do not know how to hold and play cello, you can do this without problems by using Sonic Pi.
23.2.3 How to use Mathematica
Here we will use the case to explain how to use “notebook” in Mathematica.
23.2.3.1 How to Write Program in Mathematica
● Entering and executing script
23.2.2 Getting Started
Mathematica can be used in windowing environment and also in Terminal environment.
23.2.2.1 Starting in Desktop GUI Environment
You can run the program using [Mathematica] menu or icon in the desktop or application menu. You can alos do the same thing by running “mathematica” command on the Terminal screen.
