Nearly all values are true. False is reserved for a select few values like 0, '0' and ''.

Roboticus@Roboticus-PC ~ $ perl 0 is false 0 is false foo is true bar is true fkento is true true is true false is true yes is true no is true is false Roboticus@Roboticus-PC ~ $ cat #!/usr/bin/perl use strict; use warnings; for my $t (0, qw(0 foo bar fkento true false yes no), '') { print "$t is ", ($t ? 'true' : 'false'), "\n"; }

Remember--text strings are just strings, even if they say "false" or "true". You should read the perldata (third paragraph after 'scalar' heading) for the basics.


When your only tool is a hammer, all problems look like your thumb.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
