"For a record length greater than 2,147,483,639 bytes, the record is
divided into subrecords. The subrecord can be of any length from 1 to
2,147,483,639, inclusive.

"The sign bit of the leading length field indicates whether the record
is continued or not. The sign bit of the trailing length field
indicates the presence of a preceding subrecord. The position of the
sign bit is determined by the endian format of the file.

"A subrecord that is continued has a leading length field with a sign
bit value of 1. The last subrecord that makes up a record has a leading
length field with a sign bit value of 0. A subrecord that has a
preceding subrecord has a trailing length field with a sign bit value
of 1. The first subrecord that makes up a record has a trailing length
field with a sign bit value of 0."
