# REBOL Cheatsheet ## Overview REBOL is a high-level programming language that is designed to be easy to learn and use. It has a number of unique features that make it a powerful tool for developing applications. ## Variables Variables in REBOL are created using the `set` function. Here's an example: ``` set my-variable 10 ``` ## Functions Functions in REBOL are defined using the `function` keyword. Here's an example: ``` function [a b] [ return a + b ] ``` ## Loops REBOL has several types of loops, including `for`, `while`, and `until`. Here's an example of a `for` loop: ``` for i 1 10 1 [ print i ] ``` ### Conditionals REBOL has several types of conditionals, including `if`, `either`, and `case`. Here's an example of an `if` statement: ``` if x > 10 [ print "x is greater than 10" ] ``` ## File Manipulation REBOL has built-in support for file manipulation. Here's an example of how to read a file: ``` file: read %myfile.txt print file ``` ## Resources Here are some resources for learning more about REBOL: - [The REBOL Programming Language](https://www.rebol.com/) - [REBOL Tutorial](https://www.tutorialspoint.com/rebol/index.htm) - [REBOL Cookbook](https://github.com/rebol/rebol3/wiki/Cookbook)
