<i>EAGLE Help</i>
<h1><center>Definitions</center></h1>
<hr>
The data items to be used in a User Language Program must be defined
before they can be used.
<p>
There are three kinds of definitions:
<ul>
<li><a href=198.htm>Constant Definitions</a>
<li><a href=199.htm>Variable Definitions</a>
<li><a href=200.htm>Function Definitions</a>
</ul>
The scope of a <i>constant</i> or <i>variable</i> definition
goes from the line in which it has been defined to the end of the current
<a href=216.htm>block</a>, or to the end of the User
Language Program, if the definition appeared outside any block.
<p>
The scope of a <i>function</i> definition goes from the closing
brace (<tt>}</tt>) of the function body to the end of the User Language
Program.
