1. "Module:"
It means similar to the "class library" in other languages, which is to encapsulate some commonly used fixed methods (APIs) into "modules" to achieve the purpose of compilation and multiple calls.
2. Writing - Packaging - Calling: (Window Development)
1. Steps: Create a new "Window Easy Language Module" to write a subroutine;
2. Note: Do not modify some parameters automatically generated by the compiler;
3. The written subroutine is only available to be called by external programs;
4. After writing and debugging the programs in the module, use the "Program -> Configuration -> Program Name" menu item to set the module program name, and it is best to provide notes at the same time.
5. In the last step, compile the module file with the suffix of `.ec` and save it;
6. Use: Right-click the module file in the `module reference table in our program, and you can use the subroutines exposed in the module in the program;
