  1. Simple question, why "Multiply" operator works, and "Equal" does not. compiler give error "[dcc32 Error] Project1.dpr(33): E2015 Operator not applicable to this operand type" program Project1; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils; type TMyRecord2 = record public class operator Equal(const a: TMyRecord2; const b: array of Integer): boolean; class operator Multiply(const a: TMyRecord2; const b: array of Integer): TMyRecord2; end; class operator TMyRecord2.Equal(const a: TMyRecord2; const b: array of Integer): boolean; begin Result := True; end; class operator TMyRecord2.Multiply(const a: TMyRecord2; const b: array of Integer): TMyRecord2; begin Result := a; end; var b: boolean; r: TMyRecord2; begin try r := r * [10]; // this line is compiled b := r = [10]; // this line is not compiled except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.
