// 1) target page of window ("/trousered/ragged/philanthropist.htm")
// 2) name of window ("Daisy")
// 3) Number of times window should appear (integer - if zero, the window will appear every time)
// 4) width of window (integer)
// 5) height of window (integer)
// 6) Features switch ["all" (all normal features enabled)|"none" (no features enabled)|"resize" (no features but resizable)|"scroll" (no features but scrollbars enabled)|"yes|no" (toolbar - first attribut of list)]
// 7) location bar ("yes|no")
// 8) status bar ("yes|no")
// 9) menubar ("yes|no")
// 10) scrollbars ("yes|no")
// 11) resizable ("yes|no")
// 12) directories ("yes|no")
