ok so that is my code but when i run the game doesnt run. 1) can some one tell me what Array Subscript Is Out Of Range means and 2) how can i fix the problem?
(i m a noob at this whole turing thing so i m srry if i m asking stupid questions )

It says it's out of range, because your using the wrong quotation marks.
its ' instead of "

code:

if chars2 ('d') then

You forgot the 2 after slimey, its needs to be slimey2

code:

slimex := maxx / 2 slimey := 20 slimex2 := maxx / 2 slimey := 20

Looking good so far though. But you may want to make your slimes smaller, and your x-length of the screen longer.
