That sounds good Nadya! I was considering doing something like that. It might save me a lot of time. I'd like to see the code. I assume you are using some trick like 'use again', to get the cursor to be updatable?
I will email you.

Does it just handle _a or does it handle multiple occurrences - _b _c and also, I have a vague memory that vfp handles things differently if the column name is 10 chars???

>For cases like this we have a special post-processing altering table structure code. It changes all columns with _a to just fieldname. Send me a letter to work, I'll send you the code on Monday.

But this results in very long query statements. I wrote a little routine to retrieve all of the column names for a given table into a formatted select string, and put it on the clipboard. This helps speed things up, but I still would be able to use select *.
