Greg,

Good, Sometime questions may trivial to you, but I need to have a base to
compose a solution.  If I can solve the problem.

So an entry like;

FSL5    ^NOAAPORT
        FILE    data/noaaport/test.np


Doesn't produce any output?  I'm trying to create a generic entry to see 
if any data can be captured by pqact. An observation, the date looks
future wrong, ie 1999056232  If this is an date?

That's a good question.  Does FLS have any sample pqact entries that they
could share with you. It might help our guessing here.

Yep, They create a complete WMO type of product from the NOAAport stream
to be handed off to the LDM.
