I used for loop to count it and I think it's much better 

s := o -> g(o, x[0], y[0])

h := [][];
for i to 100 do
    h := h, [s(i)];
end do;
h := [h];

pointplot(h, color = red, symbolsize = 15, view = [-2 .. 2, -2 .. 2]);
 

I wrote this code for loop from this post https://www.mapleprimes.com/questions/120018-Add-The-Successive-Outputs-From-A-For
