you might want to flush the input buffer right after the hasch

i mean use getch to get rid of buffered input, because otherwise the hasch will continue to return true and would skip any next menu
code:

%bad
put "Press anykey to exit"
loop
    if hasch then
        exit
    end if
end loop

put "don't press anything"
loop
    if hasch then
        exit
    end if
end loop
put "i told you not to press anything"


It is often useful to have a flush function run right before any "press any key to continue" message.

code:

procedure flush
    var c : string (1)
    loop
        exit when not hasch
        getch (c)
    end loop
end flush

i believe that input.keydown works seperate from getch.

yes, Input.KeyDown modifies it's chars array. Getch stores input in a buffer
