Showing information about multiple batches


Hyperlinks to multiple batches can be provided using the next-batches and previous-batches variables. These variables provide access to sequences of mapping objects containing information about all previous and next batches. Figure 10 implements the use of previous-batches to show hyperlinks to previous batches using starting and ending row numbers and next-batches to show hyperlinks to next batches using starting and ending words. Note that nested dtml-in tags are used to iterate over batch information. The nested dtml-in tags must use the mapping attribute because the items in the sequences, associated with next-batches and previous-batches, are mapping objects.

Use of DTML to provide links to all previous and next batches.
