Prerequisites
Before using this section, you should understand the concepts that are presented in the
following sections:
Chapter 4, “Starting with Raw Data: The Basics,” on page 51
Chapter 6, “Starting with SAS Data Sets,” on page 91
Chapter 18, “Interleaving SAS Data Sets,” on page 281
Input SAS Data Sets for Examples
The following program creates two SAS data sets, SOUTHAMERICAN and
EUROPEAN. Each data set contains the following variables:
Year
is the year in which South American and European countries competed in the World
Cup Finals from 1954 to 1998.
Country
is the name of the competing country.
Score
is the final score of the game.
Result
is the result of the game. The value for winners is won; the value for losers is lost.
The PROC SORT statements in the example below sort the data sets in ascending order
according to the BY variable. To create the interleaved data set in the next example, the
data must be in ascending order.
