<h2 id="preface">Preface</h2>
<p>This document seeks to introduce students to the world of programming. It can be used not only for technology, also drawing on other subjects, Mathematics, Physics, Music, English.</p>
<p>At the time of the first commercial computer programs were rare, the software that is the machine software was developed by the users themselves, who often programmed their own applications. It is important to recover this spirit so that students realize the importance of knowing how to program a computer to do their own programs.</p>
<h2 id="intro">Introduction to SmallBASIC</h2>
<p>Programming is the process of putting instructions on the computer to tell what functions are performed and in what order to do it. The aim of this subject began to make our first programs.</p>
<p>SmallBASIC is a language of computer programming based on BASIC. BASIC stands for Beginner’s All-Purpose Symbolic Instruction Code.</p>
<p>BASIC language is a high level, as well as C and is very suitable for beginners in the world of programming. BASIC is one of the most popular programming languages. It’s easy to learn and use, and their commands very similar to English (eg Print, Input) and its power.</p>
<p>SmallBASIC has a simple interface and many mathematical functions and graphics. It is an ideal tool for experimenting with simple algorithms and fun. It has a very simple structure for the programs, their lines can be numbered (10, 20, 30, etc.) are executed in order.</p>
<h2 id="structure">Structure of a program in SmallBASIC</h2>
<p><img src="/images/media/image3.png" /></p>
<p>We can see the line numbers and the most common commands for separate two commands on one line, use the two points.</p>
<p><img src="/images/media/image4.jpeg" /></p>
<p>Window work SmallBASIC</p>
<h2 id="editor">Program Editor</h2>
<p>In this section you will learn to work with the program editor:</p>
<ul>
<li>Enter the first program</li>
<li>Save the program file to disk</li>
<li>Recover files on disk</li>
<li>Run the program</li>
<li>Check it properly</li>
<li>Using Help</li>
<li>Leave SmallBASIC</li>
</ul>
<p>Steps to follow:</p>
<ol type="I">
<li>We will create a folder on the USB drive to store programs. For example: Basic.</li>
<li>Run the program My Computer&gt; All Programs&gt; SmallBASIC&gt; SmallBASIC.</li>
<li>The menu File&gt; New file and type the following program:</li>
</ol>
<p>Note: It is very important that you type the program exactly, otherwise the program will not work and get errors</p>
<pre><code>10 REM First program
20 CLS
30 PRINT &quot;Welcome to&quot;
40 PRINT &quot;basics&quot;: PLAY &quot;CDE&quot;
50 END</code></pre>
<ol start="4" type="I">
<li><p>Stores program previously created the directory, menu File&gt; Save File As, how Example.bas.</p></li>
<li><p>To skip this step. To retrieve the file from the program menu File&gt; Open File.</p></li>
<li><p>To run the program press the F9</p></li>
<li><p>Checking If everything is correct, you get the following result and musical notes, but revised the lines of the program and run it again.</p></li>
</ol>
<p>Welcome to the basics</p>
<ol start="8" type="I">
<li><p>Using help: Press F1.</p></li>
<li><p>To leave SmallBASIC menu File&gt; Exit</p></li>
</ol>
<p>Interesting note: In the Edit menu, we have the options: Cut, Copy and Paste, very useful in editing programs, but have previously selected the mouse or text lines.</p>
<p>Keyboard shortcuts for working with the program:</p>
<table style="width:68%;">
<colgroup>
<col style="width: 11%" />
<col style="width: 56%" />
</colgroup>
<tbody>
<tr class="odd">
<td>F9</td>
<td>Run the program.</td>
</tr>
<tr class="even">
<td>Ctrl+F4</td>
<td>Close Tabs programs or program information.</td>
</tr>
<tr class="odd">
<td>Ctrl+B</td>
<td>Stop the program (useful when it is in a loop without leaving the program)</td>
