The environment variables PERLIO, PERL_ENCODING, and PERL_UNICODE all give Perl various sorts of hints related to these matters. 1 Accessing Substrings Problem You want to access or modify just a portion of a string, not the whole thing. For instance, you’ve read a fixed-width record and want to extract individual fields. Solution The substr function lets you read from and write to specific portions of the string. $value = substr($string, $offset, $count); $value = substr($string, $offset); substr($string, $offset, $count) = $newstring; substr($string, $offset, $count, $newstring); # same as previous substr($string, $offset) = $newtail; The unpack function gives only read access, but is faster when you have many substrings to extract.

So ||= is used to set a variable when that variable is itself still false. Since the || check is a simple Boolean one—testing for truth—it doesn’t care about undefined values, even when warnings are enabled.

Don’t despair; Perl isn’t a low-level language, so lines and strings are easy to handle.
