Example of using the %help macro

The script invokes the %help macro without arguments to display general help. It then attempts to get help for a non-existent term ('xxx'), then for the %help macro itself and for 'set.vars', which could be a macro or an option. The commented lines at the beginning indicate possible integration with a SASUnit or similar testing framework, using assertions like %asserteq, %assertne, and %assertref. These commented lines are not executed.

Data Analysis

Type : AUCUNE

This script neither uses nor creates data. It only executes macro calls to retrieve help information from the SAS system.

1 Code Block

MACRO CALLS (commented)

Explanation :
This block contains commented assertion macro calls, presumably for unit tests (e.g., with SASUnit). The %asserteq, %assertne, and %assertref macros are used to check for equality, inequality, and reference existence, respectively. These lines are inactive and are not executed in the current script.

3	%*%assertne( ,%help());
4	%*%assertref( );

2 Code Block

MACRO CALLS

Explanation :
This block executes several calls to the standard %help macro. The first call without arguments displays general help for the SAS system. Subsequent calls search for help for the term 'xxx' (which is likely non-existent), for the %help macro itself, and for 'set.vars', which can be a user-defined macro or a reference to global SAS options/variables.

1	%help();
2	%help(xxx);

4	%help(help);
5	%help(SET.vars);
