7Lesson GETTinG STaRTEd WiTH MSWLogo Friends! Do you think computers can understand Hindi, English and other languages? No, computers cannot understand these languages. To interact with a computer you need a language. LOGO is one such language. Here, we will learn LOGO and meet our new friend Turtle. Let Us StartMicrosoft Windows LOGO (MSWLogo) is a simple computer language. It is usefulfor learning to program. LOGO is used for drawing figures using commands. It isalso used to type text and perform arithmetic calculations.There are several types of LOGO programming. Here, we are going to useMSWLogo. It is a free application that can be downloaded from the Internet.In this We will learn lesson • To start the MSWLogo program and identify parts of the LOGO window • Use of basic commands of LOGO and exiting the LOGO windowLOGO stands for Language of Graphics Oriented. Sir SeymourPapert and his team developed LOGO in 1967.In LOGO, the pen is called the TURTLE. It works as a pointer anddraws a line as it moves. We can draw different shapes by movingthe turtle in different ways. The LOGO turtle is represented by atriangle. It shows the position where it will start to draw.The turtle has two parts:• The upper pointed part is called Head.• The lower broader part is called Tail. 59Computer_Grade3.indb 59 7/31/2018 11:31:36 AM
DO YOU Originally, the turtle was a robot that moved around onKNOW? the floor when the user typed LOGO commands into a computer.How to Start MSWLogoFollow the steps given below to startLOGO:Step 1: Click on the Start button.Step 2: Click on All Programs.Step 3: From the list, click on MicrosoftWindows LOGO (Fig. 7.1).A LOGO window appears here(Fig. 7.2). Fig. 7.1 Fig. 7.2Let’s Learn LOGO Window PartsThe LOGO window is divided into TWO sections: Main Screen (Fig. 7.3) andCommander Window (Fig. 7.4).• The Main Screen: It is the area where every drawing is viewed by the user. It consists of: 60 7/31/2018 11:31:37 AMComputer_Grade3.indb 60
1. Menu Bar2. Title Bar3. Drawing Area• The Commander Window: It is the area where the user gives the commands. These commands make the turtle move on the main screen. The commander window has three main parts. Input Box– The Input Box is the Fig. 7.3 Main Screen area where you type the LOGO commands. You can also edit the commands in this window. Fig. 7.4 Commander window Recall list box– The Recall List box keeps a list of all the instructions typed in the Input Box. T ools– The Tool Box contains the control buttons. The Control Buttons on the right side corner are used for quick actions. The various Control buttons are: • Halt: Stops running the commands entered in the Input Box • Trace: Checks our programs for errors • Pause: Stops the LOGO program temporarily • Status: Clicking on this button gives us the turtle’s position, the thickness of the line it draws, etc. • Step: Runs the program we enter step-by-step 61Computer_Grade3.indb 61 7/31/2018 11:31:38 AM
• Reset: Clears the main screen • Execute: Carries out the commands typed in the Input Box; to execute a command, click the Execute button or press the Enter key • Edall: Opens the command editor windowBasic LOGO CommandsTo Move: FORWARD or FD is used to move the turtle in the forward direction. You can give the number of steps the turtle should move. Format: FORWARD<space><number of steps> Or FD<space><number of steps> Example: FD 90 BACK or BK is used to move the turtle in the backward direction. You can give the number of steps the turtle should move. Format: BACKWARD<space><number of steps> Or BK<space><number of steps> Example: BK 90 HOME is used to bring the turtle back to the centre of the screen. If you are drawing a figure and you type the HOME command, the turtle will move back to the starting position. Format: HOMETo Turn RIGHT or RT turns the head of the turtle towards the right side. Format: RIGHT<space><number> Or RT<space><number> 62Computer_Grade3.indb 62 7/31/2018 11:31:38 AM
Example: RT 60 LEFT or LT turns the head of the turtle towards the left side. Format: LEFT<space><number> Or LT<space><number> Example: LT 60Entering MSWLogo CommandsSTEP 1: Click in the Input Box at the bottom of the LOGO Commander Window.STEP 2: Type in the command.STEP 3: Press the Enter key or click the Executebutton at the right of the CommanderWindow. Let Us Do 1: Let’s make a square with each side being 100 units using FD and RT commandEnter the following commands. After eachcommand press the Enter key.FD 100 RT 90FD 100 RT 90FD 100 RT 90FD 100 RT 90FD 100More LOGO CommandsLet’s Clear the Screen CLEARSCREEN or CSThe CS command erases the drawing on thescreen and brings the turtle to its initial position.Format: CLEARSCREEN Or CS CLEANComputer_Grade3.indb 63 63 7/31/2018 11:31:40 AM
It does the same function as the CS command.However, it does not bring back the turtle to itshome position.Format: CLEAN CLEARTEXT or CTThis command is used to clear the Recall List Box.The CLEARTEXT will not clear the LOGO screen.The presented figure on the LOGO screen will notget erased. The short form of CLEARTEXT is CT.Format: CLEaRTEXT or CTLet’s Play Hide and Seek HIDETURTLE or HTIt hides the turtle and you can see your finished drawing without the turtle.Format: HidETURTLE or HT SHOWTURTLE or STIt shows the turtle again on the screen. ST Command works after HT command isalready given.Format: SHOWTURTLE or ST Fig. 7.5 Execution of ST Command Fig. 7.6 Execution of HT Command 64 7/31/2018 11:31:40 AMComputer_Grade3.indb 64
Exiting LOGOYou can exit LOGO by two methods:STEP 1: Type ‘BYE’ in the Command Input Box.STEP 2: Press the Enter key.OrSTEP 1: Select File in the Menu Bar.STEP 2: Click on Exit. Fig. 7.7Glossary 1.
