ZAP
Remove all records from the current database file
------------------------------------------------------------------------------
Syntax
ZAP
Description
ZAP is a database command that permanently removes all records from
files open in the current work area. This includes the current database
file, index files, and associated memo file. Disk space previously
occupied by the ZAPped files is released to the operating system. ZAP
performs the same operation as DELETE ALL followed by PACK, but is
almost instantaneous in comparison.
To ZAP in a network environment, the current database file must be USEd
EXCLUSIVEly. Refer to the "Network Programming" chapter in the
Programming and Utilities Guide for more information.
