# PASS_NEVER

*LSL constant*

```lsl
integer PASS_NEVER = 2;
```

Used with event-passing functions to ensure events are never passed from the child prim to the root prim, regardless of whether they are handled by child script handlers.

Constant groups: [PassMode](/constants/groups/PassMode/)

The applicable event group will never be triggered in the the root prim. Whether or not is handled in the child prim is irrelevant.
