Think of a switch, it is either on or off, and your picture is either one or the other.
If you didnt know before, boolean type variables have true or false.
You can use if and then statments and the boolean type to determine which pic to display.
Eg.
if (moved left) then
left := true
elsif (moved right) then
left :=false
end if

if left then
change to left pic
else
change to right pic
end if

If you plainly put change pic without a "switch"(the boolean variable changes) in the "if user pressed key" statement then the user have to hold the key in order for it stay in the changed form.

if chicken coordinates = car coordinates then
quit
end if

Thanks a lot for the help! I got it to work.

I have my opening title screen and then once you click it should go the instructions screen. It doesn't work. Any suggestions?

code:
%Opening Scene
Pic.Draw (opener, 1, 1, picCopy)
loop
    buttonwait ("down", xm, ym, buttonnumber, buttonup) %Clicking to go to Instructions
    if xm > 1 and xm < 800 and ym > 1 and ym < 400 then
        exit
    end if
end loop

Pic.Draw (instructions, 1, 1, picCopy)
loop
    buttonwait ("down", xm, ym, buttonnumber, buttonup) %Clicking to go to Instructions
    if xm > 1 and xm < 800 and ym > 1 and ym < 400 then
        exit
    end if
end loop


thats what have and the instructions dont show up all it does is make it so i have to click twice.

If you had all of them in a loop then exit the loop and do a end game animation when you either increase or decrease their x until they are out of screen, using loop and if and thens.
e.g.
code:

....
exits main loop here...

loop
car1X+=1
car2X+=2
exit when (car1X > maxx or car1X < 0) and  (car2X > maxx or car2X < 0)
end loop
