BOOL pascal ModifyMenu(HMENU hMenu, WORD idChgItem, WORD flags, 
                                      WORD idNewItem,  char *newString)

  There are five functions which Microsoft Windows 3.0 defines which
are basically front-ends to the ChangeMenu() function. MEWEL supports
these functions as well. The arguments to these functions are the
same ones as found in ChangeMenu().

  Same as ChangeMenu() using the MF_CHANGE  flag.
