Interleaving SAS Data Sets

Review of SAS Tools

SET SAS-data-set-list; BY variable-list;: read multiple sorted SAS data sets and create one sorted SAS data set. SAS-data-set-list is a list of the SAS data sets to interleave; variable-list contains the names of one or more variables (BY variables) by which to interleave the data sets. All of the data sets must be sorted by the same variable(s) before you can interleave them.
