 MAIL$_MAILFILE_DEFAULT_NAME

    MAIL$_MAILFILE_DEFAULT_NAME specifies the default file
    specification that the Mail utility should use when opening
    a mail file. The buffer address field points to a buffer that
    contains a character string of 0 to 255 characters that defines
    the default mail file specification.

    Specify a value from 0 to 255 in the buffer length field of the
    item descriptor.

    If you specify the value 0 in the buffer length field of the
    item descriptor, MAIL$MAILFILE_MODIFY uses the current default
    directory as the default mail file specification.

    If you do not specify MAIL$_MAILFILE_DEFAULT_NAME, MAIL$MAILFILE_
    MODIFY creates the default mail file specification from the
    following sources:

    o  Disk and directory defined in the caller's user authorization
       file (UAF)

    o  Subdirectory defined in the Mail user profile

    o  Default file type of .MAI

 MAIL$_MAILFILE_NAME

    MAIL$_MAILFILE_NAME specifies the name of the mail file that the
    Mail utility should open. The buffer address field points to a
    buffer that contains a character string of 0 to 255 characters.

    Specify a value from 0 to 255 in the buffer length field of the
    item descriptor.

    If you do not specify MAIL$_MAILFILE_NAME, the default mail file
    name is MAIL.

 MAIL$_MAILFILE_WASTEBASKET_NAME

    MAILFILE_WASTEBASKET_NAME specifies a new folder name for the
    wastebasket in the specified mail file. The buffer address field
    points to a buffer that contains a character string of 1 to 39
    characters.
