# 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
```
