Prompt response type
The Prompt response type allows developers to prompt users for actions without writing code.
The Prompt event handler is asynchronous, so if it appears in a chain of events, that chain is not suspended while waiting for the user's response. The prompt is displayed after the event chain that runs the Prompt event handler is completed.
You can associate a form event name with each response option. When a user selects a response, the event associated with that button is generated in the calling form.
If multiple Prompt event handlers are run in the course of a single event chain, only the last prompt is displayed.
