EXCHANGE
Because the functions of the things in the shelf set correspond to the functions of the things in the clipboard set, it is possible to substitute for each functional
element the equivalent functional element in the other set. The two sets can be fused.

To do this five complete clipboard sets and five complete shelf sets are needed.
The individual items of one complete clipboard set are inserted into four extended shelf sets, as the individual items of one complete shelf set are inserted
into four extended clipboard sets.

The original sequential procedure is carried out as far as possible in each set. The object inserted from the other set attempts to function like the object it
replaces.
