[EpiData-list] Access violation when comparing duplicate files

Dear all,

I am trying to compare the duplicate files. I did it for each section. In some sections with small number of fields and just integer, the comparison goes well. But in other sections with larger number of fields, the program always shows the message “Access violation” and ask whether I will ignore it and continue and kill the program. I always choose to ignore and the program seems to work on something. But nothing has really happened.

Should I just wait, because the program is still working? Or should I fix something in the entries?

I would be very grateful if someone could suggest me what to do.

Kind regards, Suparee
