2. Save the script as scalarnum.pl in the PERLSCRIPTS folder.

   

   Here’s what each line of the script does:

• #!/usr/bin/perl
  print "Content-Type: text/html \n\n";

  # The code below makes it easy to change
  # numbers output by the script.

  $cars_on_lot = 100;

  print "<p>Welcome to <b>ACME AUTO!</b></p>";

  print "<p>Which one of our $cars_on_lot cars is right for you?</p>\n";
