Download MSWLogo

After downloading and installing the software, click Help> Demo and follow the instructions . This article will give you a few examples of what MSWLogo can do.

Step 1: Move the turtle

First, you will see a turtle located in the center of the screen. Getting started is simple. In the command prompt window, type in the box: Forward 50 .

Click the Execute button or press Enter on the keyboard, do this after typing everything into the command line window. This command will draw a line as long as 50 foot steps. Easy, right?

Note: You can shorten the command, for example, Forward 50 to FD 50.

If you want to line straight to the right, instead of pointing up, type:

RT 90 FD 50

This command rotates the turtle 90 degrees to the right and the turtle will move forward 50 steps.

When the screen becomes cluttered, type: clearscreen or CS (short). This command will clean up the screen and erase everything you've drawn and, at the same time, move the turtle to the upside.

If you want to rotate the turtle to the left, type:

LT 90

Next, type the command backward:

Back or BK 50

The turtle will step back 50 steps.

When there are too many commands from within the command prompt, type:

Cleartext or CT

Now you know all the basic commands of the MSWLogo programming software.

Step 2: Create a process for MSWLogo

Process (sequence of actions) is the steps the turtle will draw or create something. You can run the process by typing its name into the command line window.

To create the process of drawing squares on the screen. Click File , then, edit it in the main window, then type a new process name. Specific steps are as follows:

Type: Square , then Enter or OK . Click later from Square and press Enter . Continue typing:

FD 50 RT 90 four times

Then, click File save and exit .

In the command line window, type procedure Square> Execute . Then, the tortoise will draw a 50 x 50 x 50 x 50 square.

Now click Edall in the command line window and go to the square of the newly created process, delete the FD 50 RT 90 command .

Repeat the above steps again but type the shorter command:

[Repeat 4 FD 50 RT 90]

Now click File save and exit . Move to the command prompt window, type Square again and press Enter . The turtle will draw a square on the screen.

Once you know how to draw a square, you can easily create another shape. For example, to draw a triangle, change 4 FD 50 RT 90, to:

Repeat 4 FD 50 RT 120

Step 3: Setxy coordinates

The main screen of MSWLogo is like an invisible grid. You can move turtles to different positions by typing the coordinates.

• The x coordinate moves the turtle left and right.
• The coordinates y move the turtle up and down.

In the command prompt window, type:

Setxy 100 100

Then press Enter .

The turtle moves to the 100 coordinates of both x & y.

The software can then perform a different process, for example, Draw a square.

Step 4: Penup and Pendown

In this step, you will know that the turtle in MSWLogo is like a pen. At the command prompt, type:

Penup or PU (abbreviated) and FD 50

Then press Enter . This command will lift the turtle's pen. The turtle moves forward 50 steps but does not draw anything.

To put the stinger of the turtle down, type:

Pendown or PD

Now the turtle will draw pictures when moving.

Step 5: Create a window

MSWLogo will create a window containing clickable user buttons to run processes.

Let's start by creating a new process: Click File> Edit . Name the new process Box. Press Enter after from Box. Time to type:

windowcreate "main" mywindow "Autodraw 0 0 50 50 []

• Autodraw is the display name of the box, mywindows is the MSW Logo name used for other activities.
• 0 0 is the setxy coordinates of the box.
• 50 50 is a boxy size.

Now type in the command prompt:

Box

Then press Enter .

This command will create a window at the top left of the screen.

Next, click Edall> Enter later (windowcreate "main" mywindow "Autodraw 0 0 50 50 [])

At this step, you can create some functional buttons. First, click the Reset button in the command window to clear the box. Type:

buttoncreate "mywindow" mybutton "Square 10 20 30 10 [square]

• Mywindows is the name of the window containing the button.
• Mybutton is the name used for other actions.
• Square is the name of the button.
• 10 20 is the Setxy coordinates
• 30 10 is the button size.
• The brackets around Square notify MSWLogo to run the square creation process when clicking the button.

Now type in the command prompt:

Box

Then press Enter .

A window will be created again, but this time, it has a button.

Finally, we need to create a window close button instead of having to press reset. Go to the process box, then press Enter after the button buttoncreate .

Type:

buttoncreate "mywindow" mybutton2 "Close 10 10 25 10 [windowdelete" mywindow]

The windowdelete command will delete a window but you must type "mywindow" first to notify the window software you want to delete.

Now go to the command prompt, type in the process box again and press Enter. We will have a window containing a button to draw a square and close the window.

This is the final result.
