Parameters
| Name | Data type | Required | Description |
|---|---|---|---|
| Compile Entire Hierarchy (F) |  |
No | Compile Entire Hierarchy specifies whether to compile all VIs within the VI hierarchy of the referenced VI. The VI hierarchy includes all VIs that call the VI as well as all subVIs that the VI calls. If you set this parameter to TRUE, subVIs indicate that they were modified by displaying an asterisk (*) in their title bar the next time you open them. By default, this parameter is FALSE. |

No | Force Compile specifies whether to compile the VI even if the VI does not need to be recompiled. By default, this parameter is TRUE. |
