hi Sarah,

GetWindowText has a third parameter, ie the length of the buffer where it
can put the text

 declare integer GetWindowText in User32.dll ;
      integer hnwd, string @lpstring, integer buflen

 declare integer FindWindow in win32api ;
    string @lpClassName, string @WindowName

 local hwnd
 hwnd = FindWindow( null, _screen.caption )
 local buf, nchars
 buf = space(1024)

 nchars = GetWindowText(hwnd, @buf, len(buf))

 do case
 case empty(nchars)
  ?? 'error'

 otherwise
  buf = left(buf, nchars)
  ?buf
 endcase

Gregory
