Input + when statement?

Post subject:  Input + when statement?
First off, I can't get keydown to work at all.
I took this straight from the examples, and it won't work
code:

var chars : array char of boolean
Input.KeyDown (chars)
if chars ('t') then
    put "The T key is pressed"
end if

Is there something wrong with that?

I was also wondering if it is possible to combine some form of input with a when statement.

something like
if chars ('t') when x=300 then *do something*

you need it in a loop

ok thanks, I have that working now

but is there any way to put a when statement in that loop so it only does something when you press the button at a specific time?

Or perhaps,
code:
if chars ('t') and x >= 300 then

when statement doesn't actually have anything to do with time. It's a condition much like if, just different syntax.

Turing:

function() when condition = true

is equavalent and will behave identical to
Turing:

if condition = true then
    function()
end if

yeah, that's what I meant, and I'll mess around with

code:
if chars ('t') and x >= 300 then


I think I can get it to work...
