This variable controls whether duplicate keys are created as LINKED duplicates (the Btrieve default) or REPEATING duplicates. When set to the default value of FALSE, the Btrieve interface creates all duplicate keys as LINKED duplicates. When set to TRUE, the Btrieve interface creates all duplicate keys as REPEATING duplicates.
In cases where a large number of users are accessing files, you may experience better performance if you set this variable to TRUE. See the Pervasive documentation for information on REPEATING duplicates and why you may want to use them.
