Passing Lists to Subroutines in Perl
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
#!/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
