<TBL>.UNMARK

<TBL>.UNMARK_RANGE()

Syntax

<TBL>.UNMARK_RANGE( [ Filter as C ] )

Argument	Description
Filter	Optional. Default = .T. (all records). A character filter expression that evaluates to a logical value. Selects the records that will be unmarked.

Description

The <TBL>.UNMARK_RANGE() method is a high-level utility function used to unmark selected records in a table. The operation is performed on the records in the table pointed to by the <TBL> object pointer.

If the optional Filter is omitted, records in the current query or range are unmarked. If a Filter is included, the current query or range is ignored, and records that satisfy the Filter are unmarked.

Note : If you are unmarking records in a set with one-many child links off the parent table in which you are unmarking records, remember that if referential integrity is enabled, unmarking a parent record will result in all matching child records being unmarked as well.
