Re: To James Bott - Error Using TData

... to handle as much of the repetitive coding as possible. The philosophy was to write each piece of code only once. So, in this case, it handles all scatter and gather routines, record locking, buffering, loading and saving the data all done with multi-user compatiability. It has worked great with ...
