<a name="snippet_constant"></a>Constant Snippets
</h1>
<p>
A constant snippet defines one or more Pascal constants. They can either
be true constants or typed constants.
</p>
<p>
Each constant snippet begins with the <strong>const</strong> keyword as
the first non-space text in the source code. Comments may not preceed it.
The <strong>const</strong> keyword is followed by at least one space or
newline and then one or more constant definitions.
</p>
<p>
Here's an example of a valid constant snippet:
</p>
<pre class="source-code">const
cRangeMax = 3;
cRangeMin = 1;
cIntArray: array[cRangeMin..cRangeMax] of Integer = (42, 56, 99);</pre>
<p>
Constant snippets may refer to other
<a href="snippet_type.htm">type definitions</a> or constants, providing
they are defined in Delphi units or elsewhere in the database. The
snippet's units and dependencies references should indicate where to
find the other types and constants. Constants may not reference
<a href="snippet_routine.htm">routines</a> or
<a href="snippet_freeform.htm">freeform</a> snippets.
