- Bad: var1 = “SomeValue”
By using descriptive variable names, you can enhance the readability and comprehension of your scripts, making it easier to understand the code’s intent and functionality.
Example of Well-Organized Script
#include "Module1.au3"
#include "Module2.au3"
Func Module1_Function1()
; Code for Module 1 Function 1
EndFunc
Func Module2_Function2()
; Code for Module 2 Function 2
EndFunc
Module1_Function1()
Module2_Function2()
This example demonstrates the use of modules and functions to organize the script into logical units. The main script imports the necessary modules and calls the required functions, ensuring code reusability and maintainability.
