First of all, do you mean you want to remove the drawn card from the deck, so
it won't be drawn again? or want to remove a card from the screen?
(1)
-----------------------------------------------------
-- function draw returns a hand of <<count>> cards
-----------------------------------------------------
function draw(integer count)
object hand
hand = {} -- empty
for i = 1 to count do      -- however many cards were requested
    x = rand(length(deck)) -- pick a card at random from remaining deck
    hand = append(hand, deck[x]) -- add that card to your hand
    deck = deck[1..x-1] & deck[x+1..length(deck)] -- remove card from deck
    if length(deck) < 1 then exit -- not enuf cards
    end if
end for
return hand
end function

If you're asking how to erase cards from the screen, you can call
repaintWindow(MainWindow) to erase the screen to the background color.
If you only want  to remove _one_ card, you'll have to erase the screen and
then re-draw all cards except the removed one. You can put your card
drawing routine in the window's onPaint event, so the cards will be redrawn
automagically whenever the window is repainted, moved or resized
Nobody said this stuff wasn't confusing :)
