&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A &amp;#039;&amp;#039;&amp;#039;variable&amp;#039;&amp;#039;&amp;#039; is a named location which provides for a series of instructions to be executed in sequence. A function in APL serves the purpose of both a function or procedure in other high-level languages such as C or Pascal. Functions are of three kinds: [[niladic]] (has no arguments); [[monadic]] (has one argument specified to the right of the function name); or [[dyadic]] (has an argument to the right and to the left of the function name. &lt;br /&gt;
&lt;br /&gt;
Like [[variable]]s, functions in APL in general, and NARS2000 in particular, come in two flavors: user functions and system functions.&lt;br /&gt;
&lt;br /&gt;
==User Functions==&lt;br /&gt;
User functions come into existence when the creator of a workspace creates the function. Th rules for naming a user function are as follows:&lt;br /&gt;
&lt;br /&gt;
-- Do later --&lt;br /&gt;
&lt;br /&gt;
==System variables==&lt;br /&gt;
System functions are created by NARS2000 when the program starts. They begin with the quad symbol &amp;lt;apl&amp;gt;{quad}&amp;lt;/apl&amp;gt;, and one or more letters. The current list of system functions is as follows:&lt;br /&gt;
