Example code : Compare
different and identical points

var

begin
// Set up
the start and end points
start := Point(1, 2);
finish := Point(3, 4);
// Is the
start point equal to the finish
point?
if PointsEqual(start,
finish)
then WriteLn('1,2
= 3,4')
else WriteLn('1,2 <>
3,4');
// Try
using PointsEqual with identical
values
if PointsEqual(Point(2,9),
Point(2,9))
then WriteLn('2,9
= 2,9')
else WriteLn('2,9 <>
2,9');
end;
