        I am writting a small application for the Mac with some friends of mine
and we want to have a menu called "Windows" that will display all the windows
that there are currently on the screen.  One problem I have is that there does
not seem to be a command "DeleteMItem" whereas there is one called "AppendMItem"
The way I was thinking to do that was to have a linked list of all the window
titles and append them.  But in order to do that I have to delete first all the
existing titles n that menu.
        Does anyone has an alternative on that that is willing to share with
me?  Thank you for your help in advance.

Excuse me if there is one before this that got thru, my editor choked..
Anyway according to my inside mac DA there is a specific function for
exactly what you need.

PROCEDURE DelMenuItem (theMenu: MenuHandle; item: INTEGER);

    DelMenuItem deletes the specified item from the given menu.

    Note:  DelMenuItem is intended for maintaining dynamic menus (such as
	   a list of open windows). It should not be used for disabling
		  items; you should use DisableItem instead.

Interface:

Menu Manager Definitions.

CONST
  noMark        = 0; { mark symbol for MarkItem }
  TextMenuProc  = 0;

  { menu defProc messages }
  mDrawMsg        = 0;
  mChooseMsg      = 1;
  mSizeMsg        = 2;


TYPE
	MenuPtr    = ^MenuInfo;
	MenuHandle = ^MenuPtr;
	MenuInfo   = RECORD
		     menuId: INTEGER;
		     menuWidth: INTEGER;
		     menuHeight: INTEGER;
		     menuProc: Handle;
		     enableFlags: LongInt;
		     menuData:   STR255;
		     END;
