How do i get the while command to work.  I want the car to turn left when the left key is held down. and then similarly to back, forward and right.  I'm just trying, not sure anyone would have reason to know Alice.  This is for a class.

Thanks

I'm not familiar with Alice. But in the languages I've used to do similar things, you wouldn't use a while statement; instead, one technique would be to start turning left when the left key is pressed; and then stop when either that key is released, or a key to counteract it is pressed.
So it's really a set of state variables, and if-statements.

Hopefully that gives you an idea..?

It looks like there are a lot of resources out there:

http://www.alice.org/community/ - Online Foums; good place to find your answer
http://www.dickbaldwin.com/tocalice.htm - Alice Tutorial - Go to http://www.dickbaldwin.com/alice/alice0930.zip for sample files
http://www.developer.com/java/other/article.php/3673761 - Introduction to Alice Programming - this is a really good one-page tutorial

For a car turning left, right, or accellerating/braking, I would check out this page, which has a download link for an Alice file:  "i made this in like 5mins before class, just something to make the time go by, all you do is use the arrow keys to move the car, (spacebar puts a boost in your speed) then once you hit the end of the road (or just when you feel like seeing it) hit N and watch the car turn into something cool."
