A customer maintenance form in Uniface 10, part 10 - a CSV import with a dry run, and backing up a SQLite file Uniface keeps o

Part 8 wrote customers to a CSV file. The obvious next request is the reverse: "we have a list from the trade fair, can you load it?". And once an import can write a hundred customers in one click, the next question follows immediately: "and how do I get back to yesterday if it went wrong?". So this part has two services: IMPORT_CUSTOMERS reads the export format back, validates every line with the existing business rules, and writes a log that says per line what happened. A dry run shows that log without changing anything.
