his 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.
