define the title of the window in beasScript style
You can define placeholder with "<..>", example <translate:Artikel> <str_parm.s_parm1>
With "title()" the system redraw the tile and replace place holders
window.title='<translate:Artikel> <str_parm.s_parm1>';
let s=window.title; return current title
//...
// Later redraw again...
window.title();
