This example demonstrates how to define and use a simple function in ProBuilder to perform a division operation. The function takes two parameters and returns their division result. This is particularly useful for encapsulating calculations that you need to reuse multiple times within your code.

Code Snippet:

// Function definition in "fonction_division" indicator
resultat = A / B
return resultat

// Calling the function in the main code
resultat = CALL "fonction_division"[A,B]

Explanation:
The code snippet above is divided into two parts:
1. Function Definition:
– The function is defined in an indicator named “fonction_division”.
– It accepts two external parameters, `A` and `B`.
– The operation performed is a simple division of `A` by `B`.
– The result of the division is stored in the variable `resultat`.
– The function then returns the value of `resultat`.

2. Function Call:
– In the main code, the function is called using the `CALL` keyword.
– The function “fonction_division” is referenced by its name and is passed the parameters `A` and `B` within square brackets.
– The result of the function call (i.e., the division of `A` by `B`) is stored in the variable `resultat` in the main code.

Step-by-Step Explanation:

• Define the function: Start by creating a function in a separate indicator. This function should perform a specific task, in this case, dividing two numbers.
• Set parameters: Specify parameters that the function will use. Here, `A` and `B` are the parameters for division.
• Perform the operation: Inside the function, write the code to perform the division and store the result in a variable.
• Return the result: Use the `return` statement to send the result back to the caller.
• Call the function: In your main code, use the `CALL` statement to execute the function with specific values for `A` and `B`, and capture the output in a variable.

This method of using functions helps in keeping your main code clean and manageable, especially when the same piece of code needs to be executed multiple times with different inputs.
