Description

The SET PCUNIQUE command causes unique indexes to be treated in the same manner as dBASE. When PCUNIQUE is set ON, it ’hides’ records with the same key value in the UNIQUE index file. Duplicate records can be added to the UNIQUE index file but will not be displayed. However, the GOTO command will still position the record pointer on the record. When SET PCUNIQUE is OFF, duplicate records cannot be entered into the UNIQUE index file. If the attempt is made from the FORMS system, an error message is displayed, and a new index key can be entered, or the [ABANDON] key pressed. If the attempt is made elsewhere, then an error is returned. The default for PCUNIQUE is OFF.

Example

set pcunique on
append from temp
