Next moves the row cursor maintained within result to the next row in the table.

If the new Row is a valid row containing table data, Next returns true.  If the new row is beyond the end of the table, Next returns false.

In a newly created Result module the row cursor is on the row before the first row containing data.  Therefore a call to Next is required to read data from the first row.

The row cursor can be moved back using the Previous command.
