Transactions works in ADS with DBFs just perfectly. Without ADS you'd have to implement the logic your self. For example:

Code: Select all  Expand view

Try

while ok
   copy record to tempfile
   delete record
   skip
endwhile

catch
  restore records to original file from tempfile
end



Hope this helps.
