Nadya,
Given these cicumstances I would probably create a record-level rule. You could call a stored procedure (or a program), pass the alias that is being updated, replace modidate with datetime() in alias and return .T. to make sure the rule validates. See the help topic Using Visual FoxPro - Programmer's Guide - Working with Data - Creating Databases.

Rules are called for every modification to and insert into that table and they are administered by the database engine so you know it will always be fired for every user.

HTH.

My question is: how can I determine, which records were actually updated? I want to replace modidate field with datetime() for these particular records.

>>Nadya,

> So, as you can see, I want to replace modidate with datetime() for editted records. Of course, it would be non-accurate in this scenario, because I can open my table, make few changes, go to lanch, then return, do some other changes and then save. If I can do it directly while editting the record, it would be better. That's why I thought about triggers also. I'll also put default value into modidate, but it will care only of new records, not for updated...
