I use "chain" from @wlf all the time processing and have not had any 
problems.
Having said that, I would like to not have to use the "chain" command and 
use "call" instead but have not figured out how to do wef and wlf 
processing.
I remember John posted a way to do it a while back.  Maybe he can re-post it 
or maybe someone else knows how to do it.
