Sample 24742: Create a new data set from multiple data sets based upon sorted order
Use the SET and BY statements to interleave data sets.
Note: Interleaving uses a SET statement and a BY statement to create
a new, sorted data set from multiple data sets. The number of
observations in the new data set is the sum of the number of
observations in the original data sets. The observations
in the new data set are arranged by the values of the BY
variable(s) and, within each BY-Group, the order of the data
sets in which they occur, including duplicates.
To interleave, data sets need to be in sorted order or indexed
on the BY variables.
