SET NEAR Command

  • 项目

Determines where the record pointer is positioned after FIND or SEEK unsuccessfully searches for a record.

SET NEAR ON | OFF

Parameters

  • ON
    Positions the record pointer on the closest matching record if a record search using FIND or SEEK is unsuccessful. With this setting, RECNO( ) returns the record number of the closest matching record, FOUND( ) returns false (.F.), and EOF( ) returns false (.F.).
  • OFF
    (Default) Positions the record pointer at the end of the table if a record search using FIND or SEEK is unsuccessful. With this setting, RECNO( ) returns the number of records in the table plus 1, FOUND( ) returns false (.F.), and EOF( ) returns true (.T.).

Remarks

A search is unsuccessful when no record meets the search criteria.

Issuing RECNO( ) with an argument of 0 returns the record number of the closest matching record if a search is unsuccessful, regardless of the setting of SET NEAR.

SET NEAR is scoped to the current data session.
