The Define Block primitive specifies up to 32 random blocks of data
elements. The blocks are referenced by number, ranging from 1 to 20 (hex).
A block, once defined, can be redefined to a different data element type and
location by simply specifying that block number, and then providing the
required information for a new block. A block can be restored to the initial
state of "undefined" by setting the NNNN field to zero.
