The function DbSkipper() is a utility function for displaying data records from a work area in a TBrowse or XbpBrowse object. It must be set as the skip block of the browse object and makes provides default behavior for the movement of the record pointer. Unlike DbSkip or the command SKIP, the function DbSkipper() returns the number of records actually skipped in the data source. In addition, DbSkipper() contains logic to prevent the record pointer from being moved on the so-called "phantom" record.
Also see the function TBrowseDb() for more information.
