Description

The ZAP command permanently removes all of the records from the active table, without affecting the table structure. ZAP is equivalent to DELETE ALL, followed by PACK. The ZAP command can only be performed on a table that is open for exclusive use. The ZAP command is typically used to reinitialize a 'transaction' table, or a journal file. ZAP also resets the table SEQNO to zero.

Any index files that have been associated with the active table are also reinitialized. Once a table has been 'zapped', there is no way of recovering the records that were previously contained in it. You should always use this command with caution.
