Yes, but use normal single quotes if it is just a string:

<dtml-call expr="RESPONSE.setCookie('guest', 'B')">

Your final idea here is probably the one you want, as it would not erase the
prevoius cookie before your guest had chosen a new one.
<dtml-call expr="RESPONSE.setCookie('guest', 'C')">

for erasing cookies : set them to expire some point of time in the
past. There might even be a method RESPONSE.expireCookie('guest') ,
but you will have to check the API docs for this..

hint : Don't get started too much on DTML. Use python-scripts for
things like this, and ZPT for presentation.
