   as, to stack hay, cornstalks, or grain; to stack or place
   wood.

   {To stack arms} (Mil.), to set up a number of muskets or
      rifles together, with the bayonets crossing one another,
      and forming a sort of conical pile.

Stack \Stack\, a. [Icel. stakkr; akin to Sw. stack, Dan. stak.
   Sf. {Stake}.]
   1. A large pile of hay, grain, straw, or the like, usually of
      a nearly conical form, but sometimes rectangular or
      oblong, contracted at the top to a point or ridge, and

   4. (Arch.)
      (a) A number of flues embodied in one structure, rising

      (b) Any single insulated and prominent structure, or

stack
     
         (See below for synonyms) A data structure for
        storing items which are to be accessed in last-in first-out
        order.
     
        The operations on a stack are to create a new stack, to "push"
        a new item onto the top of a stack and to "pop" the top item
        off.  Error conditions are raised by attempts to pop an empty
        stack or to push an item onto a stack which has no room for
        further items (because of its implementation).
     
        Most processors include support for stacks in their
        {instruction set architecture}s.  Perhaps the most common use
        of stacks is to store subroutine arguments and return
        addresses.  This is usually supported at the {machine code}
        level either directly by "jump to subroutine" and "return from
        subroutine" instructions or by {auto-increment} and
        auto-decrement {addressing mode}s, or both.  These allow a
        contiguous area of memory to be set aside for use as a stack
        and use either a special-purpose {register} or a general
        purpose register, chosen by the user, as a {stack pointer}.
     
        The use of a stack allows subroutines to be {recursive} since
        each call can have its own calling context, represented by a
        stack frame or {activation record}.  There are many other
        uses.  The programming language {Forth} uses a data stack in
        place of variables when possible.
     
        Although a stack may be considered an {object} by users,
        implementations of the object and its access details differ.
        For example, a stack may be either ascending (top of stack is
        at highest address) or descending.  It may also be "full" (the
        stack pointer points at the top of stack) or "empty" (the
        stack pointer points just past the top of stack, where the
        next element would be pushed).  The full/empty terminology is
        used in the {Acorn Risc Machine} and possibly elsewhere.
     
        In a list-based or {functional language}, a stack might be
        implemented as a {linked list} where a new stack is an empty
        list, push adds a new element to the head of the list and pop
        splits the list into its head (the popped element) and tail
        (the stack in its modified form).
     
        At {MIT}, {pdl} used to be a more common synonym for stack,
        and this may still be true.  {Knuth} ("The Art of Computer
        Programming", second edition, vol. 1, p. 236) says:
     
          Many people who realised the importance of stacks and queues
          independently have given other names to these structures:
          stacks have been called push-down lists, reversion storages,
          cellars, dumps, nesting stores, piles, last-in first-out
          ("LIFO") lists, and even yo-yo lists!
