Special help:
The icons or buttons on the left of the screen:

A Right Click with the cursor works to give added features on the following things: LogoFlower.jpg

    On a turtle it tells the turtle's name and gives you a box to type procedures like flower to do when someone clicks on a mouse.
    On a music button LogoMusic.jpg to edit the music -- notes, tempo, or volume!!

LogoBoyGirl.jpg To change the turtle into a star or other figure:
SETSH XX or SETSHAPE XX where XX is the shape number. To find the shape numbers click on the dog button and pause the cursor over the shape you want. I lingered on the moon shape. -->

LOGO Objects buttons and boxes:
When you click on a button at the left of the screen and move your cursor to the right, it changes shape into a hand. Where you click the hand, the icon you selected on the left is dropped into that location. All these button things are called objects. To delete an object use the command REMOVE "the object name e.g. REMOVE "Button1. When you place the curser on the title of an object, it turns into a hand and you can reposition the object. This does not work for buttons. If you want to change an object right click on the symbol above the name. If you do this for a melody object, you get a keyboard to make or edit a tune. The curser on the note line can be used to erase a note or add a note in the middle of your melody.

How do you use a slider to set the speed of some action?
Sliders have names - the default name for the first slider is slider1. The command to find what the slider is set at is SHOW GET "SLIDER "VALUE. This reports the value of the slider on the command line. To use the value to control action use the GET "SLIDER "VALUE in the place of turtle steps. E.g.
   FD GET "SLIDER "VALUE - there is a short hand way to do this: FD slider1

How do you play a melody that you created?
Just type the name of the melody - do NOT use PLAY, just Melody1. This is a melody object that you play just as you would do a procedure.

How do I get HELP that is NOT in the pages in this notebook?
LOGO contains a nice selection of help topics under help. I find that it takes me some time to understand what the help is explaining. So I often work with Help on the command line before putting these commands into a procedure. These helps can be printed for your easier inspection!

See the help on the neat command FREEZEBG at the right! LogoFreezebg.jpg

You can make hot colors on the playpen when you are in Draw Mode. Right click on the color and you can do turtle commands when a turtle goes into that color area. LogoColor.jpg
