You might also write a function that checks for a form by find_form, and if it finds one, return true, else return false. This allows the calling program to control any parameters etc for the open_form...

if form_already_opened ('my_form') then

   go_form('my_form');
else

   open_form ('my_form',...para_list)
end if;

function form_already_opened (fv_form_name varchar2) is

lv_form_id form;
lb_form_found boolean := false;
begin

   lv_form_id := find_form(fv_form_name);    if not id_null(lv_form_id) then

        lb_form_found := true;
   end if;

  return lb_form_found;
end;

Hope that helps...
