ENABLE Reference Manual

ENABLE ATTRIBUTES

DELETE Attribute

The DELETE attribute indicates whether the application can, or

cannot, delete records from the file that a box represents. The

syntax for the DELETE attribute is:

-----------------------------------------------------------------

| |

| DELETE { ON } |

| { OFF } |

| |

| ON |

| |

| indicates that the application can delete records from the |

| data base file. |

| |

| OFF |

| |

| indicates that the application cannot delete records from |

| the data base file. |

| |

| The starting value of the DELETE attribute is ON. |

| |

-----------------------------------------------------------------

Considerations

If the value of DELETE is ON, the value of the READ attribute

must also be ON. ENABLE imposes this restriction because an

application must read a record before that record can be deleted.

An application cannot delete records from entry-sequenced or

unstructured files. If DELETE is set to ON for a box that

represents such a file, ENABLE sets DELETE to OFF when the box is

added, and issues a warning message.
