SWITCHES

Declaration

    switch SW(1:5)

    N1N5b          define bounds

    $7SW,6,1,0     Define switch descriptor

Label Definition

    SW(3):

    N3             Stack index

    _7             Define label

    Note that a switch label may be redefined later if the
    first definition corresponded to a default definition
    e.g.

          switch T(1:3)
                  N1N3 b $5T,6,1,0
          T(2):
                  N2_5
          T(*):
                  N1_5 N3_5
          T(3):
                  N3_5

Switch Jumps


    ->SW(L)
    
    @4             Stack index descriptor

    W7             Jump to the switch '7', index on top of
                   stack.

    NOTE:          Both '_' and 'W' remove the index from
                   the top of the stack.
