Hi Gilbert,

Sorry!  I misunderstood your question.  I thought you were saying
something had changed between the versions, and you wanted to go back to
the old way.  

Also, I learned that the 'usePil' variable only applies to WMO feeds. 
So using it with the AFOS feed will not make a difference.  I apologize
for the misinformation.

As you probably know, NWWS is not a stream to which we subscribe, so
it's a low priority item for us.  If you have a sample of the new
products (without the PILs) you could always test pqing with it and see
what happens.  I'd try two tests: in one call the feed 'AFOS' and in the
other call it 'WMO' or 'DDS'.  This is to see how our two routines,
scan_afos and scan_wmo, work with the new product.  I have no idea
whether the code will need to be modified, as I do not have a sample of
the product.

I'm currently swamped, what with workshops happening in a month.  After
that I would be willing to spend a brief amount of time to see if I
could get it to work easily if you could provide me with some sample
data.  But, this wouldn't happen until mid-August.  Are the PILS are
going away some time in September?

Anne
