Please look into references and pass the arrays as references. See: http://perl-begin.org/topics/references/ (NOTE: perl-begin.org is a site I originated and still maintain.). Some comments about your code: > Thanks > > my @pets = ('dogs' , 'cats' , 'horses'); > my @numbers = (1..10); > > &study (@pets , @numbers); 1. There's already a built-in function called study so please pick another name: http://perldoc.perl.org/functions/study.html 2. Please don't call subroutines with ampersands ("&"): http://perl-begin.org/tutorials/bad-elements/#ampersand-in-subroutine-calls > > sub study { > > my (@animals, @digits) = (@_[0] , @_[1]); 1. Don't subscript arrays using @array[$idx]: http://perl-begin.org/tutorials/bad-elements/#at-array-for-subscripting 2. Don't use positional arguments: http://perl-begin.org/tutorials/bad-elements/#subroutine-arguments 3. Assigning to two arrays will cause the first array to swallow all the elements. Use references.
