You're right it doesn't declare $QUERY_STRING
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>
2. what does it do
<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>
It takes the existing content of $QUERY_STRING and adds more information to it.
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>
3. can I delete it

This line appears in a couple of instances when you use specific behaviours, and it allows the UD generated scripts to pass values to other UD generated scripts, whilst preserving any values that you also might pass.
Deleting it will break any UD scripts that use it, so it's up to you, though it will also break Server Behaviours in the Server Behaviour Palette.

My advice to you would be to leave it well alone.
