Lists in Perl
What is an List?
The List is simply an ordered set of scalar data. A list name is represented with the '@' symbol. A List name cannot start with a number, but it can have the same conventional naming system.
The only difference between an Array and a List is that array refers to variable name that holds the lists, whereas List is the real data contained in it.
print "content-type: text/htmlnn";
In the above example the scalar data in the list "number" is printed in the same order as it is stored.
