The Stack-Cross-Queue

It's just, literally, a stack crossing a queue.

Let's visualize it.

      a
      b
      c
1 2 3 4 5 6 7
      d
      e
      f

The stack is a b c 4 d e f, and the queue is 1 2 3 4 5 6 7.

Note: If you pop, the queue may be splitted into 2 parts; So does dequeueing.

The instructions

$  Enqueues 0.
#  Pushes 0.
/  Transposes the SXQ.
@  Rotates the SXQ clockwise.
:  Enqueue stack top.
;  Push queue front.
.  Pop and discard.
,  Dequeue and discard.
+  Increment popped value and enqueue.
-  Decrement dequeued value and push onto stack.
&  Roll the queue.
%  Pop and enqueue; Dequeue and push.
[code] While stack top is not 0, execute code.
{code} While queue front is not 0, execute code.
