Uh, you really can't have logic operations without boolean in any language.
Perl does do boolean operations natively you just have to know what equates
to boolean true/false given Perl's auto-typecasting feature.

The answer on the page is correct. Like anywhere else non-zero is true,
zero is false. Corner cases involving typecasts from null/strings/etc
to numbers are mostly obvious.

Give us an example of what you're trying to do and we can show you how to
code it. You'll find Perl very succinct.
