how to pass a value from the calling session from attr.zoomsession

Hi Friends,

I have written a script in which I call a standard session for which I do not have source code. I am using attr.zoomsession in the "before.zoom". I need to pass a value from the parent session to the child session. If someone can help me with syntax it would be great.

I have used the below syntax to zoom.

attr.zoomcode = z.session
attr.zoomsession$ = "tipcf1501m000"
attr.zoomreturn = "tipcf100.cpft"

Thanks
