Adding Code Comments

Introduction

Comments are lines in your code that are ignored by the interpreter. They're incredibly useful for making your code easier to understand and manage.

Why Use Comments?

Comments serve several important purposes:

• Explanation: They describe what a specific section of code does, making it easier for you (and others) to understand the logic.
• Debugging: You can temporarily disable parts of your code by "commenting them out" to isolate problems during testing.
• Documentation: Comments can act as a form of documentation, explaining how custom functions work, for example.

Our system supports two main types of comments: single-line and multi-line.

// Single line comment

/* Multi
Line
Comment
*/

Single-Line Comments

A single-line comment is created by placing two forward slashes (//) at the beginning of a line. Everything after the // on that line will be ignored.

Example Code

Let's write some code and add a comment to explain it:

// This part sums two numbers
$let[num1;5]
$let[num2;10]
Result is $sum[$num1;$num2]

Output

Here's the output you'll see:

Custom Command Bot 07/29/2026

Result is 15

Notice that the comment // This part sums two numbers doesn't appear in the output.

Multi-Line Comments

When you need to comment out several lines of code, or add a longer explanation, you can use multi-line comments. These comments are enclosed within /* and */.

Example Code

Let's expand our previous example with a multi-line comment:

/*
This part sums two numbers:
num1 and num2.
It then sends the result.
*/
$let[num1;5]
$let[num2;10]
Result is $sum[$num1;$num2]

Output

Here's the bot's output:

Custom Command Bot 07/29/2026

Result is 15

As you can see, the multi-line comment did not affect the program's output.
