…. you gotta love them!
I’m rebuilding a multi-million record database, as the supplier has switched data formats.
Each step is trivial: simple to do; well documented; and a complete step in their own right… but when your processing 35 years worth of data in 64 files into 24 sub-databases, this takes time.
… and then one goes wrong!
Somewhere in 10-million-odd lines of sgml is something throwing a perl script… possible a spurious Unicode character.
