It is hard to know from your post how complex your situation or how large the text files
might become.

If the text files will fit comfortably in memory and you only want to break the file into
strings based upon carriage returns (as implied by readln) then you could just load the
file into a stringList.

Simplistically

Code:

procedure TForm1.LoadFile;
var
  myStrings: TStringList;
begin
   myStrings := TStringList.Create;
   try
     myStrings.LoadFromFile('drive\path\filename.txt');
     // Do what you want here
     // e.g. Edit1.Text := myStrings[0];
   finally
     myStrings.Free;
   end;
end;

Ofcourse, you may want the TStringList to be more permanent and be available for
interaction with the user. In such a case you might want it to be created in FormCreate.
The example I gave is just to illustrate loading the file and accessing the first line.
