Sorry for the misleading answer. "data" is not supposed to be used directly. "next-batches" returns a sequence of "DocumentTemplate.DT_In_SV.sequence_variables". Each "sequence_variables" object behaves like a mapping and exposes the items of its "data" member (and some more items derived from them), among them "batch-start-index", 'batch-end-index', and 'batch-size'.

[Zope-dev] dtml-in: next-batches
Does anybody have an example of how to use the supposed next-batches mapping returned by dtml-in? I'm trying to build a google-like pageing feature into my application, so we just show the first 5 results, then have a link to each next page, ie "1,2,3,4..."

RE: [Zope-dev] dtml-in: next-batches
I found this in some Zope documentation. It wont give you "1,2,3,4,5...10"
it gives "(1-10)(11-20)(21-30)...". Monkey with it a little and you'll get
it. Beware it will call your External Method or ZSQL as many times/10.

Re: [Zope-dev] dtml-in: next-batches
I've also discovered that setting overlap = 0 actually causes everything to overlap by 1.
