  • NAME: Database alias. When a database is opened with <MvOPEN>, it is referenced in all other database commands by the alias.

Example:

<MvDELETE NAME="db_alias">
<MvPACK NAME="db_alias">

<MvUNDELETE> removes a mark set with <MvDELETE> from the current record in the database. Undeleted records will NOT be physically deleted by <MvPACK>.

When a database is packed, physical record numbers (as provided by the recno built-in variable) are reset as required. For this reason, you should not code in a way that uses the physical record number as a unique identifier by which a record can be referred to. You may instead wish to define a database field in which you store a unique identifier for each record. For example db_alias.d.id.
