Attention : This code requires administrator privileges.

This SAS^© macro, named `_executeCMDFile`, is designed to execute a specified operating system command file. It supports checking the shell command's return code using operator and expected return code parameters. The macro encapsulates the call to an internal macro `_xcmd`, which is responsible for interfacing with the operating system for command execution.

MACRO DEFINITION

Explanation :
This block defines the `_executeCMDFile` macro. It accepts three parameters: `i_cmdFile` (the path to the command file to execute), `i_operator` (the operator for evaluating the return code), and `i_expected_shell_rc` (the expected shell return code). The macro delegates the actual command execution to the internal macro `%_xcmd`, passing the encapsulated parameters. This structure allows for controlled and parameterized system command execution.
