Hello All,

I was looking over the lesson posted by Curtis Poe & have questions I
hope somebody (maybe Mr. Poe?) can help with.

The lesson is posted here:
http://www.easystreet.com/~ovid/cgi_course/lesson_four/lesson_four_2.html

The code in question is this piece here:

17:  if ( $tainted_username =~ /^([a-zA-Z\d_]+)$/ )
18:  {
19:      $username = $1;
20:  }
21:  else
22:  {
23:      display_page( $message );
24:      exit;
25:  }

OK... The questions...

1. Why doesn't "use strict" complain about the $1 not being declared?

2. How can I filter ALL of my form input variables with this regex? Or
maybe better asked; How can this be WRITTEN to filter ALL of my form
variables at once?

Any & all enlightenment is welcome & appreciated. Thank you in advance
for your time.
