How can I store data with randint?

-----------------------------------

So I am trying to store data using random integers with the following code:
loop
    randint (x, 1, 100)
    randint (y, 1, 200)
    if item (x,y) = 0 then
        item (x,y) :=1
         itemcount := itemcount +1
    end if
    exit when itemcount = 10
end loop

so using that code, shouldn't x, y in item (x,y) be replaced with the random integers, and then the value of the specific random integers receive the +1?  Currently, even using that code, while trying to check the value of (x,y) within a for loop, every single item (x,y) = 1, which I assume is because of that line not storing the data for the random integers, but just the variables?  So my question is, how should I change / fix this, so that the values are stored for specific random integers?

Thanks

item is an array

[code]var item : array 1 .. 100, 1 .. 200 of int[/code]

your checking if the (x,y)th element of item is 0, so is there a case where it isn't 0?

the problem in your code is that you're just naming the element. you're not actually assigning anything to that element.

for i : 1 .. 10
randint x,1,5
arrayx (i) := x
end for
