=item $/
The input record separator, newline by default. Works like B<awk>'s RS
-variable, including treating blank lines as delimiters if set to the
-null string. You may set it to a multicharacter string to match a
+variable, including treating empty lines as delimiters if set to the
+null string. (Note: An empty line can not contain any spaces or
+tabs.) You may set it to a multicharacter string to match a
multi-character delimiter. Note that setting it to C<"\n\n"> means
something slightly different than setting it to C<"">, if the file
-contains consecutive blank lines. Setting it to C<""> will treat two or
-more consecutive blank lines as a single blank line. Setting it to
-C<"\n\n"> will blindly assume that the next input character belongs to the
-next paragraph, even if it's a newline. (Mnemonic: / is used to
+contains consecutive empty lines. Setting it to C<""> will treat two
+or more consecutive empty lines as a single empty line. Setting it to
+C<"\n\n"> will blindly assume that the next input character belongs to
+the next paragraph, even if it's a newline. (Mnemonic: / is used to
delimit line boundaries when quoting poetry.)
undef $/;
=item $^W
-The current value of the warning switch, either TRUE or FALSE. (Mnemonic: related to the
