Interleaving SAS Data Sets |
-
Indexes
-
You do not need to sort unordered data sets
before interleaving them if the data sets have an index on the variable or
variables by which you want to interleave. For more information about indexes,
see
SAS Language Reference: Concepts and the
Base SAS Procedures Guide.

Interleaving data sets

For information about interleaving data
sets when they contain different variables or when the same variables have
different attributes, see Concatenating SAS Data Sets.
The same rules apply to interleaving data sets as to concatenating them.
