Forms and Hidden fields

So what is the difference between:

<input type="hidden" name="call_window" value = $ENV{REMOTE_ADDR}>


and

<input type="hidden" name="call_window" value = "$ENV{REMOTE_ADDR}">

The difference being the value being encased in quotes...but how does that
make a difference?

Or is this a Perl question and not an HTML one?

Thanks ahead...

Sorry, I forgot some about Perl , but speaking about HTML:
The specifications of SGML (parent of HTML), XML and XHTML required qoutes
around attribute values.
You may consider this as a "good style" of HTML-code design.
