The Use Once Flag
This flag, which is set during the entry of a CST, is used when it is impossible
to create entries in the table that are unique enough to allow for different
outputs according to each of the entries. This might be the case when data
extraction is done and the printable data is always preceded or followed by
the same character (or sequences).
NOTE: A positive note in using this flag is that as more CST entries get
marked as “used,” the less entries need to be checked by the
datastream adapter and the faster the conversion takes place. Even if
you do not need the flag to compensate for a lack of uniqueness in
the incoming data, setting the flag for entries that will occur only once
improves the throughput of the datastream adapter.
When the end of the CST has been reached, the used flags will need to be
reset so that this CST can be applied to the next datastream.
