Hi, the second line is simply declaring two variables: 1 - the scalar $itemtype 2 - the hash %symbol just another way to say my $itemtype; my %symbol; no magic here, *NOT* a list or data structure. A+ David Buddrige a écrit :Hi all, I am reading through a collegue's perl script. In it he has the following lines: sub SomeSubName { my ($vara, $varb, $varc, @items) = @_; my ($itemtype, %symbol); ... } The first line I understand; here you are getting the parameters to the subroutine (which are stored in @_), and putting them into particular variable names - $vara, $varb, and so on. The second line however, I am not clear what it is doing. It seems to be creating an in-line list, but firstly, that list is not assigned to anything, and secondly he is storing a hash into the list (presumably it must be a reference to a hash, since you cannot actually store a hash into a data structure such as a list or an array without using refernces... Could anyone see what possible value could be had in creating the list: my ($itemtype, %symbol); Is this assigned to some default name? thanks heaps David Buddrige. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]rg
