As long as you use modeless form, you can open reasonably unlimited number of them at the same time. When you call (CreateObject or DO FORM) a form second time, you instanciate it second time, i.e. new form object is created etc. The problem is how to arrange communication between forms. The simplest example is provided by _SCREEN.Forms collection that will keep object references to all currently existing forms. Normally, application has more extended mechanism usually called Form Manager.
