Perl: Basic Syntax
Here's some information that applies to all of perl.
Perl is free form - whitespace doesn't matter. Most people like to use
liberal indentation, but you could write all on one line, if you're a
masochist.
All perl statements end in a ; (semicolon), like C.
Comments
begin with # (pound sign)
everything after the #, and up to the end of the line is ignored.
the # needn't be at the beginning of the line.
There is no way to comment out blocks of code other than putting a # at
the beginning of each line. It's a convention taken from the shell
utilities, sorry C folks.

Example
Now our program looks like this:
#!/usr/local/bin/perl
# mailform - a simple CGI program to email the contents of an HTML
# form to a specified user.
