Variable has no value? But I put a value...

[Destro]

What is it you are trying to achieve?
I want 'C' to clear the screen. I want 'R' to restate the instructions.

What is the problem you are having?
When I run the program, it says variable has no value even though I put
var leedle : array char of boolean

Describe what you have tried to solve this problem
I have tried putting it in the loop, in the 'if' statement. Out of the loop, out of the 'if' statement. I have tried different variables. None of it works.
Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

Turing:

Please specify what version of Turing you are using
4.1.1

Thanks guys

'array char of boolean' is a type, not a value. Have a look at Input.KeyDown.

Could you explain further please? I am very new to turing D:

[Raknarg]

var num : int := 5

num's value is 5, its type is int.

I got it working, thanks guys!
