| Parameter | Type | Description | |
|---|---|---|---|
| aTable | Table | → | Table for which to test read-only state, or Default table, if omitted |
| Function result | Boolean | ← | Access to table is read-only (TRUE), or Access to table is read-write (FALSE) |
Description
This function tests whether or not the state of aTable is read-only for the process in which it is called. Read only state returns TRUE if the state of aTable is read-only. Read only state returns FALSE if the state of aTable is read/ write.
Example
The following example tests the state of an [Invoice] table. If the state of the [Invoice] table is read-only, it is set to read/write, and then the current record is reloaded.
If(Read only state([Invoice]))
READ WRITE([Invoice])
LOAD RECORD([Invoice])
End if
Note: The invoice record is reloaded to allow the user to modify it. A record that was previously loaded in a read-only state will remain locked until it is reloaded in a read/write state.
