# 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
