So.. not sure if the answer was given yet. Someone hinted, i thought, when they mentioned the ascii character set.<div><br></div><div>The 'ge' comparison operator (i think) uses the ascii table to compare strings. On the ascii table, the character 0 (zero) is not the lowest. Most non-alphanumeric characters are below zero on the table. So for example, a right bracket will be lower than zero.</div><div><br></div><div>It should be noted that, if I am right, i had to look it up. I did not know this off the top of my head.</div><div><br></div><div>- Brian</div><div><br><div><div>On Oct 10, 2008, at 10:52 AM, <a href="mailto:grand-rapids-pm-list@pm.org">grand-rapids-pm-list@pm.org</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">Here's something that tripped me up that I thought I'd share as a Perl Puzzle...<br><br>Q1: For what value(s) of $a do the following comparisons return different results?<br><br>$a >= 0<br>$a ge 0<br> <br>Q2: Ok, it isn't hard to guess.
