|
base-frame-ID |
Clears item locks only for a file identified by its base frame ID. |

Description
Item locks are set primarily by the READU, READVU, and MATREADU statements in mvBASIC programs. They prevent two or more users from updating an item simultaneously.

WARNING |
Use RESET-ITEM-LOCKS with caution: it overrides the protection provided by the operating system to prevent data corruption and Group Format Errors (GFEs). |
Use the LIST-ITEM-LOCKS command to list the contents of the item locks table. For more information about item locks, see the mvBASIC User Reference Guide.
