Attention : This code requires administrator privileges.
This script defines a macro variable 'path' (initially empty) and uses the '%sysexec' command to execute shell commands. It attempts to change the current directory ('cd') and set the 'PWD' environment variable. This allows direct interaction with the host operating system of the SAS© session. The use of %sysexec may require administrative privileges or be restricted by the 'XCMD' configuration.

« Using %SYSEXEC is the most direct way for the SAS Macro facility to communicate with the operating system without starting a DATA step. This technique is often used to prepare the environment—such as creating directories or setting system flags—before the main SAS processing begins. »
