ReadLn problem Newbie Question

[Chief1Oar]

Hello everyone, I am new to Pascal and I am trying to write a dll that reads lines of text from a text file. I have Assigned the file and path.

When I compile I get the following error...

Error: Incompatible types: got "untyped" expected "AnsiString"

the code:
//-----------------
library TestLib;

{$mode objfpc} {$H+}

uses

  sysutils, Dialogs;

var
  filhand:   text;
  fPathNam: string;
//---------         ----------------//         
function ReadInputFile(): string; stdcall;
var
   instring: ansistring;
begin
   if not Eof(filhand) then
         result := ReadLn(filhand,instring)   //error points to this line     
     else
        result := 'EOF';
end;
exports
      ReadInputFile;       

Can someone please tell me what I am doing wrong.. (I know it's got to be simple    )

Thank you
Chief

When did ReadLn change into a function?

Code: Pascal  [Select][+][-]

1.   //...
2.   ReadLn(filhand,result)
3.   //...

Thank you for the help...
