POKEUNSHIFT axmud-object-property, expression
POKEUNSHIFT axmud-object-property

   Synopsis:
      Adds a value to the beginning of an Axmud internal list property

   Notes:
      POKE gives Axbasic scripts access to some of Axmud's internal data (see
         the help for the POKE statement for a full explanation).
      POKEUNSHIFT is similar to POKE, but it only modifies list properties such
         as "world.current.doorPatternList". It cannot be used to modify a
         scalar property such as "world.current.longName", a hash property such
         as "world.current.currencyHash" or a Perl object such as
         "world.current".
      POKEUNSHIFT adds the value of the expression to the beginning of the list.
         If you don't specify an expression, the Perl special value 'undef' is
         added to the beginning of the list.
      Much of Axmud's internal data is read-only, and cannot be modified with
         POKE or with this statement. If you try to modify a read-only property
         you will get an 'operation failure' error.

   Warning:
      Do not try to modify Axmud's internal data unless you know what you are
         doing. Read the Axmud manual before you try to POKE anything. (The
         examples below are safe, but backup your data first.)

   Examples:
      ! Add a new door pattern to the beginning of the existing list
      POKEUNSHIFT "world.current.doorPatternList", "You bump into the door"
