ZeroFile command¶

Include: Use Db\DBCommands.pkg

Purpose¶

Clears all records from the storage represented by a DD.

Syntax¶

ZeroFile oDataDictionary
ZeroFile oFirstDD oSecondDD

How it works¶

• ZeroFile oDD sends ZeroFile to oDD.
• Multiple DD arguments recurse left to right.
• On success, the DD no longer has a current record.
• ZeroFile is destructive; reserve it for temporary, setup, or administrative storage flows.

Example¶

ZeroFile oScratchCustomerDD
Clear oScratchCustomerDD
Find GT oScratchCustomerDD.Customer_Number

After clearing storage, the follow-up find leaves Found=False when no rows remain.
