Business Basic does a short list of things extremely well, and it has been doing them without
drama since before most enterprise software existed. Keyed record access that pulls one
customer out of 1,344,450 in 2 ms, against 3,665 ms for a full scan of the same file.
Decimal arithmetic that gets money exactly right — no floats, no rounding drift, no
reconciliation argument on the first of the month.
Then there's data entry. A trained operator on an 80×24 screen, hands never leaving the
keyboard, will outrun any web interface you put in front of them. You can time it. Nobody
enjoys the results of that experiment.
And underneath all of it: thirty years of business rules that still ship product every day.
The pricing exceptions. The customer who gets their own freight table. The reason that one
item never goes on backorder. All of it encoded, tested by two decades of daily use, and
correct.

building nobody should ever be asked to retype.
