>>Um... there was one thing but that was just a little marketing thing: the customer code was four digit. And I'd warn the users about that, and would usually say "once you get to have more than 9999 customers, I'll just jump in and widen the field for free". Since most of my customers were small businesses, very few among them had more than 200 customers total, so the talk of 9999 customers sounded like a dream to them :).

>Thanks Dragan. That last idea ... seems that there was a lot of that pre year 2000 with date fields if my memory serves me... <bg> not done for free though.

That, not of course. But it was nice to imagine having a customer who has 9999 customers... so I (speaking Serbian) "let the flea to them". Who knows, had the times not gone globally for the worse, it may have come true.
