PC logo It is a computer programming language. The logo is built with a turtle drawing system. The PC logo can intuitively learn the running process of the program by sending commands to the turtles. Therefore, it is very suitable for being used as an enlightening programming language tool for children's computer education. Its original purpose is to teach children computer programming skills.
The simplified Chinese version of PC Logo 4.0 is easier to operate and use. You can use PC Logo 4.0 Green CN.exe without installing and decompressing it.

Introduction to Software Basics

The simplified Chinese version of PC Logo is a small drawing software and a computer programming language. It has a set of turtle drawing system built in. By sending commands to turtles, it can intuitively learn the running process of the program. It is very suitable as an initial programming language tool for children's computer education, It was designed primarily to teach children computer programming skills.

Software features

1. Instructions related to movement: "forward", "backward" and "homing". The forward command can make the turtle move forward a certain number of units, for example, after executing the "FD (Forward) 50" command, the small turtle will move forward 50 units; The backward command can make the small turtle move backward. If the "BK (backward) 50" command is executed, the direction of the small turtle will not change, but will move backward 50 units; After executing the homing command, the turtle will return to the central position of the drawing area and face the top of the screen regardless of the current position and direction.

2. Directions related to turning: "Turn right" and "Turn left". The right turn command allows the small turtle to turn a certain angle to the right as required. For example, if the "RT (right turn) 45" command is executed, the small turtle will turn 45 degrees to the right; The left turn command allows the small turtle to turn to the left. For example, if the "LT 45" command is executed, the small turtle will turn 45 degrees to the left. These commands can drive the turtle to rotate a certain angle around its center.

3. The commands related to control include REPEAT, IF... THEN... ELSE... (conditional execution), etc. If you execute REPEAT 4 [FORWARD 200 RlGHT 9O], you can draw the square in Figure 2. If you directly combine the move command with the turn command, you will write more statements, but you will repeatedly use the "Forward 100" and "Right 90" commands four times.
