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.
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
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
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
EXAMPLE: T CIRCLE
repeat 8 [fd 50 lt 90 fd 20 rt 90 fd 20 rt 90 fd 60rt 90 fd 20 rt 90 fd 20 lt 90 fd 50 rt 90 fd 20 lt 10]
