File-level descriptions

A file-level description must always appear as the first lines in a DDS statement before any record-format information. If a file contains keywords which are coded at the file-level, they will apply to all record formats within the file.

DDS allows the following types of file-level descriptions:

Specification Type
Function
Keyword
Applies to all record formats within the file.
Record
Defines a record type within the file.
