   Array of words describing the keys on which you plan to sort. The
   key_buffer argument is the address of an array containing the key
   descriptions.

   The first word of this array contains the number of keys
   described (up to 255). Following the first word, each key is
   described (in order of priority) in blocks of four words. The
   four words specify the key's data type, order, offset, and
   length, respectively.

   The first word of the block specifies the data type of the key.
   The following data types are accepted:
