Nadya,
What kind of file is the result file? How and when do you put the data to the result file?
If the result file is a table (with a memo field), why can't you put the changes there as they happen?
>For each record I keep some notes about what changes were done. I also want to keep the history of the whole file, so I need accumulative notes, which I then send to a result file.

>Originally I just created a form's property to keep accumulative notes.

I don't really understand what you were doing. Hopefully the answers to the above questions will help...
>So, I got rid of this form property, I now create a temp cursor in the Init of the class curNotes (Notes M)
