fetchNext

Procedure that repositions the query of the data-source to the first row of the next page.

Location: wbtable.p

Parameters: None

Notes:

This procedure totally overrides the fetchNext in webrep.p and contains the logic necessary to move the cursor forward from the Web page’s current row to reposition to the row that appears on the top of the next page.
The reason that this function is named fetchNext and not fetchNextPage is to simplify the interface and conceal navigation details from the caller.
