[Zope] dtml-in and batches

[Duncan Booth]

I may be missing something obvious here, but if I use the in tag to 
iterate over a list in several batches, how can I easily work out what 
*all* the batches are.

The user guide gives several examples using either previous-
batches or next-batches to list the batches before and after, but if I 
want the complete list of all batches I seem to have to do a lost of 
work, first iterating over the first batch extracting the first and last 
elements, then iterating over the next batches, all of which seems 
unduly messy.

The reason I want to do this is to build an index page with all the 
individual batches listed.

P.S. In an earlier thread Evan Simpson wrote:

When using #in with 'next' or 'previous' options you have to use a 
variable name.
