You can use the following basic syntax to use IF OR logic in SAS:

data new_data;
set my_data;
if team="Cavs" or points>20 then cavs_or_20 = 1;
else cavs_or_20 = 0;
run;

This particular example creates a new dataset with a column called cavs_or_20 that takes on the following values:

• 1 if the value in the team column is equal to Cavs” or if the value in the points column is greater than 20.
• 0 if neither condition is met.

The following example shows how to use this syntax in practice.

Example: How to Use IF OR Logic in SAS

Suppose we have the following dataset in SAS that contains information about various basketball players:

/*create dataset*/
data my_data;
    input team $ points;
    datalines;
Cavs 12
Cavs 24
Warriors 15
Cavs 26
Warriors 14
Celtics 36
Celtics 19
;
run;

/*view dataset*/
proc printdata=my_data;

Suppose we would like to create a new dataset with a column that takes on the following values:

• 1 if the value in the team column is equal to Cavs” or if the value in the points column is greater than 20.
• 0 if neither condition is met.

We can use the following syntax to do so:

/*create new dataset*/
data new_data;
    set my_data;
    if team="Cavs" or points>20 then cavs_or_20 = 1;
    else cavs_or_20 = 0;
run;

/*view new dataset*/proc printdata=new_data;

The new column called cavs_or_20 uses IF OR logic to determine if each row in the dataset should have a value of 0 or 1.

For example:

• The team name in the first row is Cavs” so the cavs_or_20 column takes on a value of 1.
• The team name in the second row is Cavs” so the cavs_or_20 column takes on a value of 1.
• The team name in the first row is not Cavs” and the points value is not greater than 20 so the cavs_or_20 column takes on a value of 0.
