The following example defines three keys:
key (4,5,p,10,5,c,20,2,ad,40,2,a,46,10,c)
The first key, the primary key, is split with its first component starting at character position 4 with a length of 5 bytes and its second component starting at character position 10 with a length of 5 bytes.
The second key (alternate key) enables duplicates, starts at character position 20 and is 2 bytes in length.
The third key is a split alternate key, with the first component starting at character position 40 with a length of 2 bytes and the second component starting at character position 46 and with a length of 10 bytes.
