Всем спасибо, сделал.
Если кому интересно, вот правильный код программы:

Код:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs;

type
  TForm1 = class(TForm)
  private
    { Private declarations }
  public
    { Public declarations }
  end;

 var
  Form1: TForm1;
  t: TStream;
  i:integer;
  m: array[1..10] of double;
  f: textfile;
 { Name_g : array[1..255,1..255] of string;  }

 implementation

{$R *.dfm}

begin
  t := TMemoryStream.Create;
    for i:= 1 to 10 do
      m[i]:= (i)*(3.475*2.875);
        begin
          AssignFIle(F,'D:\тест\file.txt');
          Rewrite(f);
            for i := 1 to 10 do begin
              Writeln(f, m[i],';');
            end;
          CloseFile(f);
        end;
      t.Free;
end.
