DevZap

Zaps a device. If a database device is zapped, all records are deleted. If an ASCII file is zapped, the file is truncated to 0 (zero) length. Use this function when you want to delete all records in a database or file without deleting the actual file.

For SQL devices, this function is a blocking Cicode function.
