Attention : This code requires administrator privileges.
This SAS© script demonstrates a robust method for temporarily managing SAS© environment options. It captures the current values of 'CENTER', 'NUMBER', and 'DATE' options into a macro variable. Then, it modifies these options (disabling them in this example) before the execution of a 'user' code block. Finally, it restores the options to their initial values, ensuring that the changes do not affect subsequent operations in the SAS© session.
Data Analysis
Type : N_A
This script does not process or generate data. Its purpose is the management of the SAS execution environment.
1 Code Block
MACRO / OPTIONS
Explanation :
This block saves the current values of the SAS system options 'CENTER', 'NUMBER', and 'DATE' into the macro variable '&saveOptions' using the '%sysfunc(getoption())' function. Then, it modifies these options by disabling them ('nocenter', 'nonumber', 'nodate') for the subsequent code.

2 Code Block
N/A
Explanation :
This is a comment serving as a placeholder for where the user's SAS code, which depends on the specified system options, should be inserted. There is no executable code in this block.

3 Code Block
OPTIONS
Explanation :
This block restores the SAS system options 'CENTER', 'NUMBER', and 'DATE' to their original values, which were saved at the beginning of the script in the macro variable '&saveOptions'. This ensures that the SAS environment is reset to its previous state.

« Managing session options is a hallmark of professional-grade SAS programming. This script illustrates the concept of configuration encapsulation: modifying the environment for a specific task while ensuring that those changes do not "leak" into subsequent parts of the session. This is particularly vital when developing shared macros or production pipelines where consistency is paramount. »
