The record length shall be defined by the number of octets in the record, including the record label, directory,fields, and the record separator. The length is a five-digit decimal number, right- aligned with zero fill if necessary.
NOTE The record length described here is a logical record length. For practical reasons relating to machine processing of data, it is sometimes necessary to divide the information into blocks.
The record status shall be defined by a single character, to be defined in an implementation International Standard, describing the status of a record, for example new or amended. In the absence of an International Standard, special agreement should be reached between the interchange partners.
The identifier length shall be defined by one decimal digit giving the number of octets of the identifier. The first or only character of this identifier shall always be IS1 in accordance with ISO/IEC 646 or ISO/IEC 6429. If the identifier is not used, the identifier length shall be set to zero.
The base address of data shall be defined by five decimal digits, right-aligned with zero fill if necessary, equal to the combined length in characters of the record label and the directory, including the field separator at the end of the directory.
The directory map positions shall be defined by the following.
a) Octet 20: one decimal digit equal to the length in characters of the length of field part of each entry in the directory.
b) Octet 21: one decimal digit equal to the length in characters of the starting character position part of each entry in the directory.
c) Octet 22: one decimal digit equal to the length in characters of the implementation-defined part of each entry in the directory.
d) Octet 23: reserved for future use.
Each data field shall consist of indicator(s) (optional), identifier(s) (optional), data and a field separator. The presence and length of the indicator(s) or identifier(s) are determined by the indicator length and identifier length, as defined in the record label, and shall be used consistently within each data field of the record.AS NZS ISO 2709 pdf free download.
