DtoLine command makes a text line from a given D-record. See the manual DtoLine for the detail.

The command argument:

-f "chapter:/\, /:Chapter%d"

gives format of the "chapter" field. This example means:

• value of the "chapter" field is converted numeric,
• then its decimal representation is appended after the literal "Chapter".
• When the "chapter" field repeats, the delimiter ", " is appended.

Format of "word" field is not given. In this case the default delimiter TAB is applied.

Detail of the field-format-list is describe in the manual D_fmt.
