ENABLE ATTRIBUTES

FILL Attribute

The FILL attribute indicates whether the application does, or

does not, automatically read a record (or records) for a box

under the conditions described below. The syntax of the FILL

attribute is:

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

| |

| FILL { ON } |

| { OFF } |

| |

| ON |

| |

| indicates that, under certain circumstances, the |

| application is to perform an automatic read operation |

| on the file that the box represents. |

| |

| OFF |

| |

| indicates that the application is not to perform an |

| automatic read operation under any circumstances. |

| |

| The starting value of the FILL attribute is OFF. |

| |

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

Considerations

When you supply ON as a value for the FILL attribute, a generated

application can perform an automatic read operation on a data

base file. The conditions under which the application performs

the read operation depends upon the level at which the box

resides in the tree structure of the application.

For a box at the highest level of the tree structure (the

outermost box), two cases are possible:

• If the box has OFF as the value of the VALUES attribute, the

application, upon execution, automatically reads the first

record or records (if any) from the data base file.
