<p><b>Pico</b> is a <a href="Programming_language" title="Programming language">programming language</a> developed at the Software Languages Lab at <a href="Vrije_Universiteit_Brussel" title="Vrije Universiteit Brussel">Vrije Universiteit Brussel</a>, intended to be simple, powerful, extensible, and easy to read.<sup id="cite_ref-pico_d&r_1-0" class="reference"><a href="#cite_note-pico_d&r-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The language was created to introduce the essentials of programming to non-computer science students.

</p><p>Pico can be seen as an effort to generate a palatable and enjoyable language for people who do not want to study hard for the elegance and power of a language. They have done it by adapting <a href="Scheme_(programming_language)" title="Scheme (programming language)">Scheme's</a> <a href="Semantics_(computer_science)" title="Semantics (computer science)">semantics</a>.

</p><p>While designing Pico, the Software Languages Lab was inspired by the Abelson and Sussman's book "<a href="Structure_and_Interpretation_of_Computer_Programs" title="Structure and Interpretation of Computer Programs">Structure and Interpretation of Computer Programs</a>". Furthermore, they were influenced by the teaching of programming at high school or academic level.

</p><p>Pico should be interpreted as 'small', the idea was to create a small language for educational purposes.

</p>

<div class="mw-heading mw-heading2"><h2 id="Language_elements">Language elements</h2></div>

<p>De Meuter, Gonzalez, and D'Hondt describe the Pico syntax as being "two-tiered."<sup id="cite_ref-pico_d&r_1-1" class="reference"><a href="#cite_note-pico_d&r-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The first layer consists of simple rules for writing small programs in a <a href="Functional_programming" title="Functional programming">functional programming</a> style.

</p>

<div class="mw-heading mw-heading3"><h3 id="Comments">Comments</h3></div>

<p>Comments are surrounded by <a href="Backquote" class="mw-redirect" title="Backquote">backquotes</a> ("`").

</p>

<div class="mw-heading mw-heading3"><h3 id="Variables">Variables</h3></div>

<p><a href="Variable_(programming)" class="mw-redirect" title="Variable (programming)">Variables</a> are dynamically <a href="Data_type" title="Data type">typed</a>; Pico uses static <a href="Scope_(programming)" class="mw-redirect" title="Scope (programming)">scope</a>.

</p>

<pre>var: value

</pre>

<div class="mw-heading mw-heading3"><h3 id="Functions">Functions</h3></div>

<p>Functions, like everything in Pico, are <a href="First-class_object" class="mw-redirect" title="First-class object">first-class objects</a>, meaning they can be assigned to variables and passed to and returned from functions. Also, there are no anonymous functions in Pico; functions must have a name.<sup id="cite_ref-pico_d&r_1-2" class="reference"><a href="#cite_note-pico_d&r-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> For example, a function, <code>func</code>, with two parameters, <code>param1</code> and <code>param2</code>, can be defined as:

</p>

<pre>func(param1, param2): ...

</pre>

<p>Functions can be called with the following syntax:

</p>

<pre>func(arg1, arg2)

</pre>

<div class="mw-heading mw-heading3"><h3 id="Operators">Operators</h3></div>

<p>Operators can be used as prefix or infix in Pico:

</p>

<pre>+(5, 2)

5 + 2

</pre>

<div class="mw-heading mw-heading3"><h3 id="Data_types">Data types</h3></div>

<p>Pico has the following types: <a href="String_(computer_science)" title="String (computer science)">string</a>, <a href="Integer" title="Integer">integer</a>, <a href="Real_number" title="Real number">real</a> and <a href="Array_data_type" class="mw-redirect" title="Array data type">tables</a>.

</p><p>It does not have a native <a href="Character_(computing)#char" title="Character (computing)">char</a> type, so users should resort to size 1 strings.

</p><p>Tables are compound data structures that may contain any of the regular data types.

</p><p>Boolean types are represented by functions (as in <a href="Lambda_calculus" title="Lambda calculus">lambda calculus</a>).

</p>

<div class="mw-heading mw-heading3"><h3 id="Control_structures">Control structures</h3></div>

<div class="mw-heading mw-heading4"><h4 id="Conditional_evaluation">Conditional evaluation</h4></div>

<p>Only the usual if statement is included

</p>

<pre>if(condition, then, else)

</pre>

<div class="mw-heading mw-heading2"><h2 id="Code_snippets">Code snippets</h2></div>

<pre>display('Hello World', eoln)

</pre>

<pre>max(a, b):

if(a < b, b, a)

</pre>

<pre>`<span class=""><a rel="nofollow" class="external free" href="http://www.paulgraham.com/accgen.html">http://www.paulgraham.com/accgen.html</a></span>`
