Hi Jim,

>I rather suspect something else, primarily because of the history behind this issue.

It's not the product, believe me. In contradiction to some people's expectations FoxPro/DOS does not change its behavior because VFP is installed, all it relies on is FoxPro itself and the operating system. Now run the tests yourself on FoxPro 2.6, and you will see that it behaves basically the same. There are some minor differences, for example the way memory variables in a SELECT statement are treated, SET COLLATE has a little more impact, and so on, but DELETED() didn't change.

OTOH, if I look at my code now and my code I wrote 8 years ago, I can see a lot of differences. Not only, of course, do I now know more about FoxPro, but the approach has changed a lot. My early code is full of navigation right on the table. I regularily checked whether a table contained any records, I had a lot of SET RELATION stuff, I used SCATTER/GATHER to read/write to records and of course I re-used deleted records to avoid that my users have to spent an hour or so on packing all tables. After all, I was writing programs that had a total of 250 MB data, quite a bit at that time.
