Variable Data Fields

Definition and scope:

The variable data fields include fields 01X-8XX. They are grouped into blocks according to the first character of the tag , which, with some exceptions, identifies the function of the data within the record. The type of information in the field is identified by the remainder of the tag. Each field is identified by a field tag in the Directory . Within variable data fields, two kinds of content designation are used: two indicator positions stored at the beginning of each field, and a two-character subfield code preceding each data element within the field.

Heading Fields: Indicators, subfield codes, and input conventions for all the fields which include headings follow similar patterns. For detailed information, select: Headings: X00-X30 Fields .
