I tried to scan the table using Foxfix (3rd party tool) and it reports that "inordinate number of errors found .." then it says that most likely the problem is with the table header. The FF_SCAN() is suppose to fix the header problem but instead it completely trashes the table.

Another possible reason could be that the table was originally created in Clipper and maybe header is not completely VFP compatible. And I don't know how to make it into 100% VFP type table.

Do you have any suggestions, please.?
