RouterOS2.96 script details

Article Title: RouterOS2.96 script details. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Four Variables
Global-defines global variables, which can be shared by calling all scripts
Local-Defines local variables. They can only be called under the script they want and cannot be shared by other scripts.
Loop index variables-index number variable defined in for or foreach
Monitor variables-monitoring variables
