Re: [fpc-pascal] How to get to Range Check Error location

Hi Juha,

I just tried and can confirm that a LCL app running inside Lazarus
(r27491), having turned on range checks is able to perfectly catch and
show the place of an range check error (Ubuntu 10.04/AMD64). What I've
not tried, but suggest to try, is to open the Lazarus project in
Lazarus and run it as the tes app I'm talking above. Maybe then it
will show nicely also the range check error sources in Lazarus itself.

HTH

PS: The test app main form unit source

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs,
StdCtrls;

type

  { TForm1 }

  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    F: Byte;
  public
    { public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.Button1Click(Sender: TObject);
begin
  F := F + 1;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  F := High(F);
end;

end.
