When saving a noticeboard to disc, the
programmer has a choice as to whether to save only the definition
or else the definition plus the data. If only the definition is saved
then each time that the definition is restored
all items will revert to having zero lengths. However if the data
is saved as well the NBS_RESTORE_NOTICEBOARD routine can be used
to restore both the definition and the data, and a subsequent call
to NBS_SAVE_NOTICEBOARD will update the disc file so that
the next
time that the noticeboard is restored it will be in the same state
as when it was saved.
