Dont be mislead by the other answers :)
I hope you dont have to use DTML, so you
can concentrate on the recommended way.

The key here is to use the
ZTUtils.Batch class as utility for batching
(API documentation is in the ZopeBook,
there are several examples you will find
with Google.
Try not to mix it into ZPT, like some examples
show but use a small python script and
return the values from there.

Good luck
