@johnefrancis Is this where I get to pull out my example of how, as a summer student, in 3 weeks I did the job of a dozen-person department, with perl? Taking a 250 hour ETL process down to like... 40-60? And I did this in my spare time. Pro-tip: don't do your EBCDIC->ASCII conversion on the legacy hardware, while the multicore DB server is waiting.
Probably 60-80 lines of perl.
