<p><i><b>BASIC Programming</b></i> is an Atari Video Computer System (later called the <a href="Atari_2600" title="Atari 2600">Atari 2600</a>) cartridge that teaches simple computer programming using a dialect of <a href="BASIC" title="BASIC">BASIC</a>. Written by <a href="Warren_Robinett" title="Warren Robinett">Warren Robinett</a> and released by <a href="Atari%2C_Inc." title="Atari, Inc.">Atari, Inc.</a> in 1980, this <a href="BASIC_interpreter" title="BASIC interpreter">BASIC interpreter</a> is one of a few non-game cartridges for the console. The Atari VCS's <a href="Random-access_memory" title="Random-access memory">RAM</a> size of 128 bytes restricts the possibilities for writing programs.

</p>

<div class="mw-heading mw-heading2"><h2 id="Details">Details</h2></div>

<p>The <i>BASIC Programming</i> display is divided into six regions:

</p>

<ul><li><b>Program</b> is where instructions are typed. It has a maximum of eleven lines of code.</li>

<li><b><a href="Call_stack" title="Call stack">Stack</a></b> shows temporary results of what the program does.</li>

<li><b><a href="Variable_(computer_science)" title="Variable (computer science)">Variables</a></b> stores the values of any variables that the program is using.</li>

<li><b>Output</b> displays any output values that the program creates.</li>

<li><b>Status</b> shows the amount of available memory remaining.</li>

<li><b>Graphics</b> contains two colored squares that can be manipulated by the program.</li></ul>

<p>Input is given through two Atari keypad controllers, which came with special overlays to show how to type the different commands and letters.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Programs are restricted to 64 characters in size and normally 9 lines of code, limiting the programs that can be written (users can disable all windows except Program and keep selecting "New Line" until 11 lines of code are present).

</p>

<div class="mw-heading mw-heading3"><h3 id="Language_features">Language features</h3></div>

<p>VCS BASIC supports the following keywords:<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p>

<ul><li>Statements: <code>Print</code></li>

<li>Structure: <code>Goto</code>, <code>If-Then-Else</code></li>

<li>Graphics: <code>Clear</code></li>

<li>Functions: <code>Hit</code>, <code>Key</code></li>

<li>Relational operators: <code>< > =</code></li></ul>

<p>Unlike most BASIC implementations of the time:

</p>

<ul><li>VCS BASIC uses ← instead of = for assignment; e.g., <code>A←A+1</code>.</li>

<li>Statements can be strung together on a line without a delimiter; e.g., <code>Note←APrintA</code>.</li>

<li>An <code>If</code> statement can be used as a function, returning a value: <code><code class="mw-highlight mw-highlight-lang-cbmbas mw-content-ltr" style="background:none; border:none; color:inherit; padding: 0px 0px;" dir="ltr"><span class="n">Ver1</span><span class="err">←</span><span class="n">Ver1</span><span class="o">+</span><span class="kr">If</span><span class="n">Ver1</span></code><a href="Modulo_operation" class="mw-redirect" title="Modulo operation">Mod</a>2<code class="mw-highlight mw-highlight-lang-cbmbas mw-content-ltr" style="background:none; border:none; color:inherit; padding: 0px 0px;" dir="ltr"><span class="kr">Then</span><span class="mf">8</span></code><code class="mw-highlight mw-highlight-lang-monkey mw-content-ltr" style="background:none; border:none; color:inherit; padding: 0px 0px;" dir="ltr"><span class="kr">Else</span></code>92</code></li>

<li><code>If</code> statements can take an <code>Else</code> clause.</li></ul>

<p>Special variable names:

</p>

<ul><li><code>Note</code> sounds a musical note, assigned numbers from 0 to 7

<ul><li>Numbers assigned to <code>Note</code> are implicitly assigned modulus 8, thus 8 becomes 0, 9 becomes 1, etc.</li></ul></li>

<li><code>Hor1</code>, <code>Hor2</code> - the horizontal coordinate of one of two squares</li>

<li><code>Ver1</code>, <code>Ver2</code> - the vertical coordinate of one of two squares</li></ul>

<p>The language supports 26 unsigned integer variables A to Z. VCS BASIC supports integers from 0 to 99. Math operations wrap, so 99+1 becomes 0, 99+2 becomes 1, etc.
