Robert,
Fred was using "ZAP" in a generic sense. You don't use the ZAP command on the table, but simply set the grid recordsource to an empty string before making changes to the cursor. As he showed in his brief code, first you set the grid Recordsource to an empty string, update your data and then reset the recordsource to its original value.

thisform.oGrid.RecordSource = ""
*get your new data here
thisform.oGrid.RecordSource = "cursoralias"

With this technique there's no need to reset any of the column controlsource values, widths, header captions, etc.
