Conditional State WHERE Macro

This SAS^© script defines a `%where` macro that accepts a single argument, `state`. Inside the macro, the `%superq` function is used to ensure that the `state` value is treated literally, even if it contains special characters or unresolved macros. The macro uses conditional `%if/%else` structures to compare the `state` value to 'NC' (North Carolina) or '%str(OR)' (Oregon). If the state matches 'NC', 'Southeast' is displayed in the SAS^© log. If the state matches 'OR', 'Northwest' is displayed. For any other value, 'Unknown' is displayed. The script concludes with a call to the `%where` macro with 'OR' as an argument.

Data Analysis

Type : NONE

The script does not manipulate any data from SAS tables (SASHELP, external, or internally created via DATA STEP/CARDS). It operates solely on literal values and macro parameters, the result of which is written to the SAS log.

MACRO

Explanation :
This block includes the declaration of the `%where` macro and its subsequent call. The macro is designed to take a `state` argument and, through conditional comparisons using `%superq` for robustness, it displays a corresponding region in the SAS log. The call `%where(OR)` tests the macro's functionality, which should result in 'Northwest' being displayed in the log.
