# Passing Lists to Subroutines in Perl

PERLServer Side ProgrammingProgramming Scripts

Because the @_ variable is an array in Perl, it can be used to supply lists to a subroutine. However, because of the way in which Perl accepts and parses lists and arrays, it can be difficult to extract the individual elements from @_. If you have to pass a list along with other scalar arguments, then make list as the last argument as shown below −

## Example

Live Demo

#!/usr/bin/perl
# Function definition
sub PrintList {
my @list = @_;
print "Given list is @list\n";
}
$a = 10; @b = (1, 2, 3, 4); # Function call with list parameter PrintList($a, @b);

## Output

When the above program is executed, it produces the following result −

Given list is 10 1 2 3 4
