how do i tell turing that is a key is not pressed to esit a loop?
for example in my code:


loop

Input.KeyDown (key)

if key ('a') then

loop
right := false
left := true

Pic.Draw (pic1l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic2l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic3l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic4l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic5l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic6l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic7l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic8l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic9l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

Pic.Draw (pic10l, round (x - 70), round (y), picMerge)
x := x - run_s
delay (60)
View.Update
cls

end loop
end if

i want it to exit when the a key is not pressed but i don't know how to make that if statement.
how do i say to turing that is a is not pressed exit the loop?

boolean not or if - else

Here:

Turing:

if not key('a') then

Thats what Tony meant.
