Yes, it is !
Would it be good to find a function that could reconstruct the structure of dbf and could take all data and replace in a corrected structure. As FixFile of old Norton Guide. :)

In Stru.prg there is a function that recognize the type of dbf and check if memo file is missing, then it is created according the dbf type. But is creating a empty memo just to be able to open the dbf.

Hi Pablo

Thank to your interest :)

As name implied, mission of this function is only check and report validity of a .dbf file; not fix probable hazards.

As you noticed, there are clever programs, works to repair tables.

Viva HMG :D
