Basic HTML version of Foils prepared Sept 20 97
| There is a well-known problem with ordinary ways of using Perl subroutine arguments |
| If one has a argument list such as |
| (@list1, @list2, .... ), then the subroutine sees a single list (array), which is the concatenation of the component lists |
| This can be avoided using hard references with the \ operator. For example: |
| @tailings = popmany( \@a, \@b, \@c, \@d ); |
| See next foil for code of popmany |
