In order to do the actual lab exercises, you will need a program called Alice. It should be installed on the lab machines.
If you are on a lab machine, locate it now. Double click the icon to start the program and proceed to the next section (Using Alice). You can skip the rest of this section.
As stated in the previous section, if you are working on your own computer you will need to go to alice.org. You will download either Alice.dmg for a Macintosh or Alice.zip for a Windows machine. Full details are on page 2 of the textbook. (If you are running Linux you must figure it all out for yourself.)
