The level indicator FD identifies the file description entry; it must precede
the file name. All semicolons are optional, but the entry must be terminated
by a period.
Clauses which follow the file name are optional in many cases, and their
order of appearance is immaterial. See section 3 for a discussion of the
BLOCK, RECORD, LABEL, VALUE OF, and DATA clauses.
If the RECORD CONTAINS or DATA RECORD clauses are not specified, a
record area 136 characters long is automatically assigned to the file.
