### 7.13 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.
