append-check-set

Appends a group of mutually-exclusive checkable items to the menu.

• (send a-mred:menu append-check-set name-tag-list callback initial help) -> int list
      name-tag-list : list of cons pairs or strings and tags
      callback : a procedure of one argument
      initial : int
      help = null : string or null

  The name-tag-list argument is a list of cons pairs, where the car is the menu item label string and the cdr is a tag that will be passed on to callback when the menu item is selected. The initial argument specifies the position of the item that is intially checked (starting from 0); it defaults to 0. The help string is used for all of the items. The result is a list of ids generated for the menu items.
