A Perl program is a text file and it is
compiled when you run it. To create the Perl
version of the "Hello, world" program, we would
prepare a file as follows:
Filename: hello.pl
#!/usr/bin/perl
#------------------------------
# [10/30/2002] - File created.
#------------------------------
print "Hello, world!";
exit;

Note 1: Comments in Perl are everything from a # sign to the
end of a line, but the comment in the first line of
the program is special. The characters after #! tell
the name of the program to run the rest of the Perl program.
Note 2: There is no "main" routine.
Note 3: You can use any filename and extension (this program
is called "hello.pl" for easy identification only).
Note 4: This example is not a Perl CGI program.
