pageBackward

Reads the previous record from the data-source the number of times required to find the row that should be the top row in the table in order to make the current record the last record.

Location: wbtable.p

Parameters: None

Returns: LOGICAL

Notes:

This is all additional logic that makes fetchPrev and fetchLast override their SUPER.
The function is called from fetchNext if the last row is encountered as fetchNext loops through the number of records specified in the TableRows property. It finds the row that should appear on the top of the next page.
