Greetings A Perl script can be a very simple thing. Also notice the semicolon which represents the end of a Perl statement. Not all Perl statements require semicolons at the end, but it is good practice, since omitting a semicolon where one is required will definitely result in a program error. It is always a good idea to add comments to your program code, which make it easy to remember what a particular line does. Sometimes this is not obvious by simply reading the line of code.
Programming languages derive much of their power from the use of variables.
