Examples of
Standard Packages
Figure A-1 shows examples of standard send and reply packages. In these examples, a
correspondent named SMITH transmits a send package to a recipient named JONES,
who responds by transmitting a reply package to SMITH. Each package consists of a
package header item and one component item, and references its own recipient list.
Each component item contains two or three data records. The data records in a
package can have the same record type (340 or 323) as records in a recipient list, but
these records should never be confused because they serve entirely different purposes.
Recipient records typically contain delivery information that data records do not, and
specify delivery status flags, such as DELIVERED or EXAMINED, as well as other
data.
