| Syntax | UnmarkIndex IndexName [, UserLoginNameExpression] |
| Action | [Statement] Removes the current record from a query index. |
| Scope | Usable anywhere. |
| Notes | This statement removes any reference to the current record from the query index specified by IndexName. If the UserLoginNameExpression is supplied, the index instance for that user is selected, rather than the one for the current user. This powerful feature allows different user record sets on the same index to be manipulated under program control. eg Workflow systems could pass tasks between members of a group. The system workarea SysError is set to a non-zero value if an error occurs, otherwise zero. Returns SysError = 1 if the user specified is not found. |
