In most automated systems, all significant system
events are entered in a journal log. This log is a
chronological record of data processing operations,
which may be used to reconstruct a previous or updated
version of a file.
All system-level commands entered by an operator
are logged. Log entries are usually queued for delivery
to a printer as they are generated, but this is optional.
However, they are always journaled to a file from which
they can be recalled and printed at a later time, as
desired. This log gives a system operator or supervisor
the ability to review current and previous system events.
In addition, the journal log supports message
accountability. The system records the receipt of every
formal message and the termination of every formal
message delivery that it schedules.

PROCESSED OUTGOING MESSAGES
Those messages introduced into the
LDMX/NAVCOMPARS from a PCMT, VDT, paper
tape reader, data speed reader (DSR), card reader, or
magnetic tape are considered outgoing. They are
prepared in JANAP 128, modified ACP 126, or other
acceptable formats. Most outgoing messages are
destined to be delivered to distant communications
centers and commands. Others also have delivery
requirements for in-house distribution to commands
