Is there a way to halt script processing of an event without also doing a /haltdef?

If I use the "^" prefix on an event, then I can /haltdef to prevent mIRC displaying the event, or I can /halt to both /haltdef and stop the script running further, but AFAIK there is no way stop the script processing further without doing a /haltdef.

Does anyone know a way to halt the scirpt from running further without /haltdef the message?
