Usually table corruption is caused by the Network or Windows OS issues, but not by the VFP data engine.
Basocally to check the record number in the header you may do something like this:

lc=left(filetostr(tablefile),10)
?recc()=asc(substr(lc,8,1))*256^3+asc(substr(lc,7,1))*256^2+asc(substr(lc,6,1))*256+asc(substr(lc,5,1))

Best Wishes

>Sergey,
>I read the entire thread and do not like any of the solutions offered there. I am now much less confident in VFP than I have ever been. The primary task is saving data and it appears that there is an unfixed internal bug that prevents the product from doing the one thing it was designed for. What to do...
