5-: 15
elements of crunched arrays or fields of crunched records. If a type is
not in Table 5-5 , a crunched array or record cannot have elements or
fields of that type.

(* Minimum number of bits required to represent value.)
1. The value representation has the most significant bit first and
the least significant bit last (no byte swapping).
2. If a record or array contains a crunched structure, it must be
crunched itself.
