Drop unselected variables? In the Select Variables step (step 3), you selected variable
group
s to be restructured, variables to be copied, and an identification variable from
the current data. The data from the selected variables will appear in the new file. If
there are other variables in the current data, you can choose to discard or keep them.

that contain only null values.

contains the number of new rows generated by a row in the current data. A count
variable may be useful if you choose to discard null values from the new file because
that
makes it possible to generate a different number of new rows for a given row
