Scalars, Arrays, Hashes

• Scalars are like variables in JavaScript.
• Have a name, hold a piece of data.
• Start scalar names with $.  Think of the $ as the S in scalar.
• Example: $className = "Internet II";
• print $className;
• Example:  http://homepages.uc.edu/cgi-bin/cgiwrap/jonesbr/simpleperl2.pl
• It's as easy as that!  Just remember the $.
