2. The first time you run DrScheme, you need to choose a language to
run in. I recommend that you click on the following buttons as they
become available to choose the Graphics language.
Language
PLT
Graphics
OK
Pass the cursor over your function definitions in the edit area of DrScheme while holding down the left mouse button.
Move the cursor to the text box of the Automatic Tester and click the left mouse button to change focus to the text box.
Click the middle mouse button to paste the definitions into the text box.
To leave DrScheme itself, select Exit under the Files menu. If that doesn't work, click on the X in the upper right corner of the window.
