Recording of a volume Partition

7 -

A subset of those attributes shall apply to all File Sections of a file that contains records according to 6.10. If any
of those attributes are assigned to the file, an Extended Attribute Record shall be recorded in association with
each of the File Sections of the file.

The other attributes identified in an Extended Attribute Record shall apply to that File Section and all preceding
File Sections of the file (see 6.5.1). If no Extended Attribute Record is recorded in association with the last File
Section of a file, then these attributes are not specified for the file.

6.4.7

Recording of a Volume Partition
If a Volume Partition is recorded, it shall be recorded over one or more Logical Blocks, the Logical Block
Numbers of which form a continuous ascending sequence. The recording shall begin at the first byte of the first
Logical Block of the Extent. It shall continue through successive bytes of that Logical Block, and then through
successive bytes of successive Logical Blocks, if any, of the Extent, until all of the Volume Partition is recorded.
The first Logical Block of each Volume Partition shall have a Logical Block Number which is the lowest
Logical Block Number in the Logical Sector that contains that Logical Block.

The number of Logical Blocks over which the Volume Partition is recorded shall be the assigned Volume
Partition size for the Volume Partition.

6.5 File

structure

6.5.1

Relation to File Sections
Each file shall consist of one or more File Sections. Each File Section of a file shall be identified by a record in
the same directory. The sequence of the File Sections of a file shall be identified by the order of the
corresponding records in the directory.

A File Section may be part of more than one file and may occur more than once in the same file. A File Section
may be identified by more than one record in the same or a different directory.

Each File Section of a file may be recorded on a different volume.

6.5.2

Numbering of bytes in a file
The bytes comprising a file shall be numbered consecutively. The numbering shall start from 1 which shall be
assigned to the first byte of the first File Section, if any. The numbering shall continue through successive bytes
of that File Section, and then through successive bytes of each successive File Section, if any, of the file.

The numbering shall end with a number equal to the sum of the number of bytes in all File Sections of the file.

6.5.3

Contents of a file
The information in a file shall be interpreted according to the relevant standards for the coded representation of
information.

NOTE 7

The identfication of these standards is the subject of an agreement between the originator and the recipient of
the file.

6.5.4 Associated

file

An associated file has a relationship not specified by this Standard to another file that has been assigned the
same File Identifier (See 7.5) as that of the Associated File in the same directory.

6.6 Volume

Set

A Volume Set shall be the set of volumes on which a set of files is recorded.

A Volume Set shall consist of one or more volumes having common volume set identification and identifying the
same coded graphic character sets for use within selected descriptor fields (See 7.4). All volumes in a Volume Set
shall be numbered consecutively starting from 1.

A Volume Group within a Volume set shall consist of one or more consecutively numbered volumes the contents
of which are established at the same time. The sequence number of the volume that has the highest sequence
number within the Volume Group shall be the assigned Volume Set size.

Each volume of a Volume Set shall contain a description of all the directories and files that are recorded on those
volumes the sequence numbers of which are less than, or equal to, the assigned Volume Set size of the volume.
