Detection of Duplicate New Labels in Recodes
When adding new labels in a recode, any duplicated labels will be highlighted in gray and a notation in red will appear at the bottom-right corner of the screen as a notification and warning that duplicate labels are present. This feature works automatically in the recode editor. There is no action to take to use this feature, other than the normal steps to creating or updating a recode. Detection of duplicate new labels in recodes is especially useful when working with recodes that have a long list of labels.
