passing container

Hi,

I am trying to use swe_event_create for triggering a workflow. I set some variables in calling application program before calling a workflow in the event container using the following syntax:

SWC_SET_ELEMENT CONTAINER 'instln' INSTLN.

How do I access this in the workflow that is triggered? In the header data, when I bind event container to workflow container, how can I get this container variable instln in the event container there?

Thanks.
