And just to complete ikegami's somewhat terse response, you don't need to be online to look this up, it's bundled with your copy of Perl. From the command line, you can run the command `perldoc perlvar` [download] and get the documentation that corresponds to your installed version. On Unix-like systems, `man perlvar` usually works as well. • another intruder with the mooring in the heart of the Perl	[reply] [d/l]

Note that there's nothing special about variables starting with $ - all perl variables start with $, @, or %. Also, not all special/predefined variables have any other punctuation in them; there's $@ and %! but also @INC, %SIG, $a and $b. anyway. as mentioned above, they're all explained in perlvar.

To make your own code more readable, consider using the English module, which allows you to use more understandable names for the special variables. `split//,q{john hurl, pest caretaker}and(map{print @_[$_]}(join(q{},map +{sprintf(qq{%010u},$_)}(2*23074993,51016415261,7597936997,13 +177145131,3*26789167*181))=~/\d{2}/g));` [download]	[reply] [d/l]
