# How to Use IF OR Logic in SAS

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 print data=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 print data=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.

And so on.
