Assigning Values Conditionally
Categorizing Values
Suppose you want to
create a variable that categorizes the length of time that a subject
spends on the treadmill during a stress test. This new variable, TestLength,
is based on the value of the existing variable TotalTime. The value
of TestLength is assigned conditionally:
|
Value for TotalTime
|
Resulting Value for
TestLength
|
|---|---|
|
greater than 800
|
Long
|
|
750 - 800
|
Normal
|
|
less than 750
|
Short
|
To perform an action conditionally, use an IF-THEN statement.
The IF-THEN statement executes a SAS statement when the condition
in the IF clause is true.
|
Syntax, IF-THEN statement:
IF expression THEN statement;
