function PauseConsole(Prompt: PAnsiChar): boolean;
var
  hStdIn, hStdOut: THandle;
  dwRd, dwWr, i: Cardinal;
  cBuf: array [0..128] of TInputRecord;
begin
  result := false;
  hStdIn := GetStdHandle(STD_INPUT_HANDLE);
  hStdOut := GetStdHandle(STD_OUTPUT_HANDLE);
  if ((hStdIn <> 0) and (hStdOut <> 0)) then
  begin
     WriteFile(hStdOut,Prompt[0],lstrlenA(Prompt),dwWr,nil);
     while ReadConsoleInput(hStdIn,cBuf[0],128,dwRd) do
     begin
       for i := 0 to dwRd do
       begin
         if ((cBuf[i].EventType = KEY_EVENT) and (cBuf[i].Event.KeyEvent.bKeyDown)) then
         begin
           Result := true;
           exit;
