I am assuming that you are talking about an HTML form that gets submitted
to be processed by a perl application (cgi script).
perl only kicks in when the form is submitted. What you need is some kind
scripting language which can do what you are looking to do. See
http://developer.netscape.com/ for more info om JS.

Read the basic HTML tag reference on form fields. Something like
<INPUT TYPE=TEXT NAME="foo" SIZE=20 MAXSIZE=30>
will display a field of 20-character width and will let you type in a
maximum of 30 characters (scrolling to accomodate the extra chars).
