Join will compile an array into a scalar. Using the array example above, @messages, the following code will generate the string "Hello world!\n, I like perl!\n" as a scalar:

<syntaxhighlight lang="perl">my @messages = ("Hello world!\n","I like perl!\n"); my $joined_message = join(", ",@messages); print $joined_message;</syntaxhighlight>
