[fpc-pascal]files handler in FPC

[Łukasz Leśniak]

Hello!
My name is Lukasz Lesniak and I am from Poland (Central Europe). I use Pascal
very often.

I've declared structure:
(* ------------------------------------------------------------ *)
type Person = record
		name: string[20];
		.
		{something else}
		{about 40 position}
		.
		age : Word;
              end;
     SetOfPerson = ^ElemOfSetOfPerson;
     ElemOfSetOfPerson = record
                           desc: Person;
			   prev: SetOfPerson;
			   next: SetOfPerson;
			 end;	

   filePerson = file of Person;
(* ------------------------------------------------------------ *)

First I wrote my program in Turbo Pascal. Now I want
to convert source to FPC and the problem is:

(* ------------------------------------------------------------ *)
procedure ReadDataFromFile(var s: SetOfperson)
var F: filePerson;
    p: SetOfPerson;
.
.
Assign(F, path_to_F);
{$i-}
Reset(F);
{$i+}
if IOResult <> 0 then Halt(1);
while not Eof(F) do
 begin
  new(p);
  Read(F, p^.desc);
  p^.next:=s; 
  s:=p;
end;
.
.
(* ------------------------------------------------------------ *)

and trying the same in FPC

(* ------------------------------------------------------------ *)
procedure ReadDataFromFile(var s: SetOfperson)
var i, F: LongInt;
    p: SetOfPerson;
.
.
 i:=0;
 F:=FileOpen(path_to_F, fmOpenRead);
 if F = -1 then Halt(1);
 new(p);
 FileSeek(F, i, fsFromBeginning);
 FileRead(F, p^.desc, SizeOf(p^.desc));
 (* XXX *)
 p^.next:=s;
 s:=p;
 i:= i + 1;
 end;
(* ------------------------------------------------------------ *)		

XXX - question is: how to read file with FileRead function
      from beginning to end, beacause this code reads only one person!
      I am using FileSeek. It is good?
