# detach

Purpose
Detach the current model from its parent node.
Synopsis
`procedure detach`
Further information
1. This procedure detaches the model calling it from its parent model such that it becomes a main model running on a root node. As a consequence the connection to its parent model is closed, its model number is set to 0 and the node number of its instance becomes 0 (root node). The parent node is notified of the detachment by means of a termination event for the model which gets the status RT_DETACHED.
2. The operation is possible only if the hosting intance is running exclusively this model ( i.e. no submodel is loaded at the time of calling detach) and no file is open between the hosting instance or the model and its parent (in particular the default streams have to be set to "null:").
3. After a model is detached, it can no longer communicate with its parent using events or access files through the "rmt:" driver. The HTTP protocol (available through the module mmhttp) might be used as an alternative to the facilities provided by mmjobs in this case.
4. The instance running the detached model terminates automatically after the end of execution of the model.
5. This routine can only be called by a submodel running on a remote instance. It has no effect if used by a main model.
