Sample text

The Camel book contains the complete reference information, some tutorial stuff, and a bunch of miscellaneous information about Perl. There’s also a separate pocket-size Perl 5 Pocket Reference (O’Reilly) by Johan Vromans that’s convenient to keep at hand (or in your pocket). † At any hour of the day or night, there’s a Perl expert awake in some time zone, answering questions on Usenet’s Perl newsgroups—the sun never sets on the Perl empire. This means that if you ask a question, you’ll often get an answer within minutes.

Does), Perl will see the value as a string. So you don’t need to worry about the difference between numbers and strings; just use the proper operators, and Perl will make it all work. * So "12" * "3" gives the value 36. † At the extreme end of this, something that isn’t a number at all converts to zero. This would happen if you used the string "fred" as a number. Likewise, if a numeric value is given when a string value is needed (say, for string concatenation), the numeric value is expanded into whatever string would have been printed for that number.

Then it uses the variable in whatever way you requested. So the most common use of chomp looks like this: chomp($text = ); # Read the text, without the newline character $text = ; chomp($text); # Do the same thing... but in two steps At first glance, the combined chomp may not seem to be the easy way, especially if it seems more complex! If you think of it as two operations—read a line, then chomp it— then it’s more natural to write it as two statements. But if you think of it as one operation * To be honest, it’s normally your system that waits for the input; Perl waits for your system.
