On 2nd thought:
dws is right, you need to use a module or something, since the approach I list below is probably not thread-safe.
You have the right idea, when you want to generate a sequence reliably, use srand($seed), keeping $seed consistent across calls to srand. Each time you call srand() this resets the random number generator. If you want to "clear" the random number generator for more random usage, just call srand() with no seed.
#!/usr/bin/pseudocode
srand($seed);
print rand, rand, rand -> 1, 2, 3
srand($seed);
print rand, rand, rand -> 1, 2, 3
srand();
print rand, rand, rand -> 42, 256, 3.14
srand($seed);
print rand, rand, rand -> 1, 2, 3

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
