Tool script example for lua

-- Define a function named "calculate_sum" that takes two parameters, a and b
function calculate_sum(a, b)
    -- Calculate the sum of a and b
    local result = a + b
    -- Return the result
    return result
end

-- Call the calculate_sum function with arguments 10 and 20
local sum = calculate_sum(10, 20)

-- Print the result of the calculation
print("Sum:", sum)

Explanation:

1. function calculate_sum(a, b) - This line defines a function named calculate_sum that takes two parameters, a and b.

2. local result = a + b - This line calculates the sum of the parameters a and b and assigns it to a local variable named result.

3. return result - This line returns the value of the result variable when the function is called.

4. local sum = calculate_sum(10, 20) - This line calls the calculate_sum function with arguments 10 and 20, and assigns the result to a local variable named sum.

5. print("Sum:", sum) - This line prints the text "Sum:" followed by the value of the sum variable to the console.
