4. What is the TURTLE?
The turtle is drawn as a triangle in MSW LOGO. When we execute commands, the turtle will do what we type.

5. Basic Commands
There’re few commands in MSW Logo. PU - Short for "pen up," it lifts the "pen" from the screen so that moving the turtle doesn't draw a line. PD - Puts the pen down so that moving the turtle draws a line. FD [length]– Forward/Use to move the turtle forward BK [length] – Backward/Move the turtle backward LT [degree] – Turn left RT [degree] – Turn right

6. Procedure & SUBROUTINE
Procedure/Subroutine is a portion of code within a larger program that performs a specific task and is relatively independent of the remaining code. In MSW Logo, procedure is the steps for the turtle to do something. Example:
Now, you can just simply type ‘square’ and it will automatically make a square

7. The length will be the user’s input
Variables
Variables are data which can change. For example: Variables can be used to define the length of the square.
Declare the variable
The length will be the user’s input
e.g. square 100

8. Example: T Circle
Code
repeat 8 [fd 50 lt 90 fd 20 rt 90 fd 20 rt 90 fd 60 rt 90 fd 20 rt 90 fd 20 lt 90 fd 50 rt 90 fd 20 lt 10]
