### User-defined Operators in GPC

GNU Pascal allows the user to define operators according to the Pascal-SC syntax:

    program PXSCOperatorDemo;

    type
      Point = record
        x, y: Real;
      end;

    operator + (a, b: Point) c: Point;
    begin
      c.x := a.x + b.x;
      c.y := a.y + b.y;
    end;

    var
      a, b, c: Point = (42, 0.5);

    begin
      c := a + b
    end.

The Pascal-SC operators `+>`, `+<`, etc. for exact numerical calculations are not implemented, but you can define them.
