if you use the unit StrUtils there is a function called ReverseString() you can use.
If you want to keep the '-' in front use something like:

uses StrUtils;

...

function Reverse(InStr: string): string;
begin
 result := '';

 if Length(InStr) = 0 then
  exit;

 if InStr[1] = '-' then
 begin
  result := '-';
  Delete(InStr, 1, 1);
 end;

 result := LowerCase(result + ReverseString(InStr));
end;

procedure TForm1.Button1Click(Sender: TObject);
var
line1, line2: string;
begin
line1:= edit1.Text;
Reverse (line1);
end;

it compiles correctly but does not change the text

errrrrrr what the Author wants you to tell him/her is this:

procedure TForm1.Button1Click(Sender: TObject);
var
  line1, string;
begin
  line1:= edit1.Text;
  line1 := Reverse (line1);
 ***** Edit1.text := line1;  <--- This line!
end;

Or am I off the mark?

I see... PeterdeB, although you have accepted the correct solution because what I typed was the correct code that would compile and work, I am undeserving of (all?) the points.
I will not personally object if someone goes to admin to get the points re-assigned. Although it was probably an innocent mistake, it is not fair :p
