DPL Example 013
From Dpldemo
This example demonstrates how a big result set can be split into several pages. The central idea is to use the Call extension as a vehicle for calling the original page with a varying parameter for the offset. The resultsfooter is used to offer a link to the Call extension; in this link the new offset is calculated.
To avoid redundancies we use the variables extension; thus count (aka limit) and pagename can be defined at a single place.
