IF-THEN-ELSE Conditional Structure

This script illustrates the basic syntax of an IF-THEN-ELSE statement, which allows different blocks of code to be executed depending on the truthfulness of a specified condition. The placeholders '[Condition]' and '[Code goes here]' represent the conditional logic and the actions to be performed. This type of structure is fundamental for implementing logical decisions in data processing or macro programming.

Data Analysis

Type : CREATION_INTERNE

No data is explicitly processed, created, or imported in this example. The script presents a purely logical flow control structure without direct interaction with datasets or external files. The category 'CREATION_INTERNE' is used to indicate that the script does not depend on external data sources or SASHELP for its logical operation.

DATA STEP

Explanation :
This code block demonstrates an 'IF-THEN-ELSE' conditional structure. The line 'if [Condition] then do;' introduces the condition to be evaluated. If the '[Condition]' is true, the code between 'do;' and the first 'end;' is executed. If the '[Condition]' is false, the code between 'else do;' and the second 'end;' is executed. The brackets indicate reserved locations for a valid SAS condition and the SAS code to be executed, respectively.
