I have installed Java 8 but I'm not sure that Java creates a problem in my code.

Here is a piece of code that I think that creates a problem.

program new;

var
 i,s : integer;
 b,t : string;
begin
 i := 1;


 WHILE i <=19999 DO
    begin

 ClickMouse ( 390, 329, mouse_left );   //
 ClickMouse ( 390, 329, mouse_left );   //  This code taken string
 ClickMouse ( 390, 329, mouse_left );   //  in CHAT on Firefox.
 ClickMouse ( 390, 329, mouse_right );  //  Sets the ClipBoard
     wait (391);                        //  with the option Copy
 MoveMouse ( 458, 344);                 //  (right_click,
 ClickMouse ( 458,344, mouse_left );    //  then left_click Copy)

         s := Length(getClipBoard());
         b := getClipBoard();

         if s <= 3 then s := 4;
         
         
      t :=   b[s-2];
       
 i := i + 1;
   end;

end.

loop works well (10 min - 1 hour) and then report error
Error: Access violation at line

t :=   b[s-2];

Most common ERROR is displayed when the s = 0.
That's why I put a line:

if s <= 3 then s := 4;

but error(Access violation) is still sometimes displayed.

The index b[s-2] does not exist, in other words the array is either empty or does not reach that high. You should add a length check before you do t := b[s-2]

if (length(b)) = 0) then
dosomething

Thank you. I tested code 2 hours and no error. Thank you very much RJ.
