Hi Greg,

I need to add one more comment about your pqact.conf entry to our previous 
discussion.   Even if the input and output redirection were to work, (although 
we've already established that
it won't) there might be another bug.   (Or perhaps it's a feature from your 
perspective...) There may be several products that will match the ^[AF]SUS0[12] 
pattern.  For each one,
pqact.conf will spawn another my_decode.pl process.   From the way the entry is 
written, each my_decode.pl process will be trying to write to the same file.   
The results could be quite
scrambled.  FYI.

Anne
