Use records.

code:

type Position:
    record
        x, y : int
    end record

var badies : array 1..20 of Position

for i : 1..20
    badies(i).x := i*100
    badies(i).y := maxy-200
end for

Just fixing a few typos in the code...
Carry on.

Also, if you're looking to abuse the ability of poor programming, don't forget that arrays can have many dimentions...

var a:array 1..20, 1..2 of int
% 1..20 indicates unit, 1..2 is either the x or y axis.

But, you should use records instead, as already said.
