File Description Entries
The file description (FD) entry is the highest level of organization in the File Section of the Data
Division. FD clauses give the size of logical and physical records and the names and attributes of
the data records within the file. When a file is to be printed on a printer (either directly, or through
a spooler), its file description can include information about how the data is printed on a page.
The characteristics of the file determine which of the clauses are required and which are optional.
Clauses that appear can follow in any order, ending with a period after the last clause. No clause
can appear more than once. The data description entries of one or more records must follow the
file description entry.
