Hi george,

>I fail to see how anyone can claim that an SQL Server table is an ISAM. The internal sturctures are completely different. SQL Server's table are not contiguous file blocks. Each page contains information regarding the data there, plus pointers to the previous and next pages, and offesets in the individual records. By contrast, VFP's records are store in a contiguous block.

The same applies to the jet database. Is the JET database ISAM or not ISAM. I guess this depends on your definition of ISAM.

1. If you decide this is ISAM, then you must conclude that the internal structure of the physical database is not a measure of being ISAM or not. SQL servers database could be ISAM also in this case.

2. If you decide this is NON-ISAM: Fact is that the Jet database suffers from the same trips across the server. Well how that comes ? Just because the engine is seperated from the phisical database. Therefore extra trips are not an exclusive property of ISAM.

Walter,
