You can have one or more addressbooks in Pine. In addition to a
    personal addressbook, one or more global, read-only addressbooks
    can be set up (for sharing between multiple users). The names
    of your personal addressbooks are specified in the Pine resource
    file by the ADDRESS-BOOK option. Normally, this option is set
    and modified from within Pine by using the SETUP menu and then
    selecting the Addressbook menu; it can, however, also be set by
    manually editing the Pine resource file. The built-in default
    file name used for an addressbook PMDF_INIT:PINE.ADDRESSBOOK.
    A "lookup" file is used to speed access to the addressbook. The
    lookup file has the same name as the addressbook, with -LU as
    suffix; e.g., PMDF_INIT:PINE.ADDRESSBOOK-LU. The lookup file
    is generated automatically by Pine. Global addressbooks can be
    specified using the GLOBAL-ADDRESS-BOOK option.

1  –  Addressbooks and PMDF Personal Alias Database

    A limited interface between Pine's address books and PMDF's
    personal alias database has existed since Pine 3.91. When you
    add an address to one of Pine's address books using Pine's
    ADDRESS BOOK menu, it will also be added to your personal alias
    database, overwriting any existing entry of the same name. The
    Pine "nickname" is the alias name used in PMDF's personal alias
    database and the e-mail address is the corresponding value for
    the alias. Adding or deleting Pine's address lists has no effect
    on PMDF's personal alias database.

    When you delete an address in one of Pine's address books, it is
    also deleted from PMDF's personal alias database if present.

    The J command can be used to dump the entire current addressbook
    into your PMDF personal alias database. If no personal alias
    database exists, it will be created.
