8.63. English

Provides aliases for the Perl built-in special variables. Everything else about the variables and their use remains the same. Be aware, though, that using the English module significantly slows down a program for regular expressions.

Some of the Perl variables match some awk built-in variables. For those cases, you'll find two English names: a short version (which is the awk name) and a longer version. For example, you can use either $ERRNO (the awk name) or $OS_ERROR to refer to the Perl variable $!.

Here is the list of variables and their English alternatives:
