Some schemes demand that ringers record and submit these data, others donot. Where schemes do not record such items, records should be submitted with the appropriatecode <strong>for</strong> unknown or unrecorded (usually U, Z or a hyphen) rather than just leaving a blank characterspace.<strong>The</strong> fields which have been added in the 2000Plus code often do not have a value <strong>for</strong> unknown/unrecorded; missing values are represented by two adjacent 'pipe' symbols.3.9 Derived data<strong>The</strong> <strong>EURING</strong> code provides three fields <strong>for</strong> derived data. <strong>The</strong>se are <strong>for</strong> the distance moved, directiontravelled and time elapsed since ringing. For the ringing event, these fields must all contain hyphens,not zeros. This provides one simple way of separating the ringing record from subsequent records.Some schemes have found difficulty in calculating the distance and direction fields. <strong>The</strong>se can becalculated by the EDB when the data are loaded. In these cases they should be left as hyphens in therecovery/recapture record. However, always calculate the elapsed time.<strong>EURING</strong> exchange-code 2000 Enhanced 42 - 42
