READ Attribute
The READ attribute indicates whether the application can read a
record or records from the data base file represented by the box.
The syntax for the READ attribute is:
-----------------------------------------------------------------
| |
| READ { ON } |
| { OFF } |
| |
| ON |
| |
| indicates that the application can read a record or |
| records from the data base file. |
| |
| OFF |
| |
| indicates that the application cannot read a record or |
| records from the data base file. |
| |
| The starting value of the READ attribute is ON. |
| |
-----------------------------------------------------------------
Considerations
You can generate an application that cannot read any records for
a box. You do this if you supply OFF as a value for both READ
and FILL. A box of this sort may be used for inserting records
only.
If the value of either UPDATE or DELETE is ON, then the value of
READ must also be ON.
