Published on :
The script defines two distinct macro variables, 'First' and 'Second', with character strings. Then, it creates a third macro variable, 'both', by concatenating the values of the first two. Finally, it uses the %PUT macro to display the content of these variables in the SAS© log, demonstrating the expansion of macro variables.
Data Analysis

Type : CREATION_INTERNE

The data manipulated are character strings assigned to macro variables directly within the script. No external data source or SAS dataset is used.

1 Code Block
MACRO STATEMENT Data
Explanation :
This block uses the %LET statement to define the macro variables 'First', 'Second', and 'both'. The 'both' variable combines the values of 'First' and 'Second'. The %PUT statement is then used to write literal text and the values of the macro variables ('First', 'Second', 'both') to the SAS log, allowing their content and expansion to be verified.
