I would have the decoder (runDecoder.ksh) read the data-product from standard-input because that way is more efficient than invoking pqcat(1) in the decoder script and less prone to error. Also, the pqact(1) process will notice that it couldn't pipe the data-product to the child decoder process and will, I believe, try to do this twice before giving up -- which might explain the behavior you're seeing. > Scott Regards, Steve Emmerson
