Mods to the second phase spreadsheet were completed yesterday - far more easily and quickly than I would have ever imagined. Short test indicates they work as intended. I did the mods in two stages; the second reduced the spreadsheet size by about 4% - and, still, the spreadsheet runs about 220Mb in size. Data entry goes smoothly, though. Error traps work. The database is ready to build.

I can go back and continue work on Phase I, which could turn into a monster should all permutations be explored. The database is flexible enough to handle it. All I have to do is write the control files.

All going well - for a change.
