Attention : This code requires administrator privileges.
This macro checks for the existence of a source file specified by the 'from' parameter. If the file exists, it executes a system command via the 'x' instruction to copy it to the 'to' destination, potentially renaming it. The system command syntax ('copy', use of backslashes, '/y' flag) is specific to Windows environments and may require adaptation for a SAS© Viya™ environment on Linux. The code also depends on an external macro '%AHGfilename'. The use of the 'x' command requires the XCMD option to be enabled on the server.
Data Analysis
Type : EXTERNE
The script manipulates physical files directly via the operating system, without using SAS libraries.

MACRO
Explanation :
Macro definition. It declares local variables, calls a utility macro (%AHGfilename), checks for the existence of the source file with %sysfunc(fileexist), and executes the copy via an 'x' shell command if the condition is met.
