Foil 28 Some Remarks about Subroutines - V -- Separating Arguments

From Perl5 and Advanced Perl4 Features Computational Science for Information Age Course CPS616 Material -- April 16,1996. by Geoffrey C. Fox
1 There is a well known problem with ordinary ways of using Perl subroutine arguments
2 If one has a argument list which is
3 (@list1, @list2, .... ), then subroutine only sees a single list (array) concatenating the component lists
4 This can be avoided using hard references with \ operator and shown by example
5 @tailings = popmany( \@a, \@b, \@c, \@d );
6 See next foil for code of popmany
