I have a process that is continually scanning large logs so whatever I do has to be very efficient (preferably built in stages).
I want to select all records into the primary output stream where columns 82-86 are a valid (leading zero) whole number. I also have to select on columns 78-81 being one of 3 values - but this would be easy in a separate stage. Clearly, I could write my own stage to do this but I was hoping there would be something more efficient. Does anyone have any ideas. Colin Allinson Amadeus Data Processing GmbH
