take text files and parse into mailing counties my office receives 8 million addresses in 7 text files with non-standard delimiters once the files are received, a manual process was used to create seperate documents for each of the California mailing centers (16 of them) with a 17th being Reno Nevada I started with creating an array of the first 3 digits of each necessary county, but ran into parsing issues. I then posed my issue to StackOverflow, where TheMadTechnician was able to provide a better solution. This currently chews up ram like no-ones business and takes about 3 hours to complete.
