Further, I can retrieve a menu item from the menu, but am also at a loss as to how to retrieve my submenu at a stage in the future. I have a feeling that there is something very simple that I am not understanding here, and would be very grateful if someone could point me in the right direction.

"anItem" is a pointer to the menu item to which you wish to connect the submenu.
I was working on code to do this yesterday, and I saw this method, but I preferred instead to just use the -setSubmenu method of my menu items. What you might not be understanding is that you attach a menu to the submenu property of a menu item. You don't add a submenu to a menu as you seem to have put it above.
In either case, in the future, when you want to get the submenu, you can send the -submenu message to your menu item that has the submenu attached to it in order to retrieve the submenu.
If you don't know which menu item has a particular submenu that you are interested in, you can search through them, or you could set the tag of the menu item of interest and find the item that has that tag at some later time using NSMenu's –itemWithTag: method.
Definitely read the menu programming guide and and NSMenu and NSMenuItem class descriptions and I think you'll find that menus are one of the most straightforward parts of Cocoa to understand._______________________________________________
