The ACTION specifier indicates the allowed I/O operations for the file connection. It takes the following form:
ACTION = act
| 'READ' | Indicates that only READ statements can refer to this connection. |
| 'WRITE' | Indicates that only WRITE, DELETE, and ENDFILE statements can refer to this connection. |
| 'READWRITE' | Indicates that READ, WRITE, DELETE, and ENDFILE statements can refer to this connection. |
The default is 'READWRITE'. On Windows NT (including Windows 2000) and Windows 9* systems, the default can be affected by a compiler option. For more information, see your Programmer's Guide.
