* If you plan to use time(), use Time::HiRes instead. It provides more uniqueness and also seems to execute faster than time().
Time::HiRes::time indeed provides more uniqueness, but it is not faster:
Benchmark: running Time::HiRes::time, time, each for at least 1 CPU se
+conds...
Time::HiRes::time: 2 wallclock secs ( 0.82 usr + 0.22 sys = 1.04 CP
+U) @ 1071260.58/s (n=1114111)
time: 0 wallclock secs ( 0.70 usr + 0.31 sys = 1.01 CPU) @ 18
+16838.61/s (n=1835007)
Rate Time::HiRes::time time
Time::HiRes::time 1071261/s -- -41%
time 1816839/s 70% --
sorry, only way I could figure out how to deal with time "slipping". After $inc == MAXINC
Try the modulo operator %. Example increments:
($counter += 1) %= 5; # 0, 1, 2, 3, 4, 0, 1, 2..4, 0..4, 0..4, ...
($counter += 1) %= 256; # 0..255, 0..255, ...

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).
