Hello everybody, I sometimes get an error message "Error reading record" when I open an Epidata *.rec file. ......... I believe, that this error only happens with data files that I received as email-attachments.

My suggestion that in situations where you want to e-mail the rec file to another place, send it as a zip file. Some systems adds one line or a blank line to attachments, so I would:

One of a-c. a From tools menu make an archive and send it - preferably encrypted, such that contents are not giving problems if the e-mail gets lost or sent to an inappropriate receiver.

b. Save data file(s) etc. in a new compressed zip-file, include current date in filename: AFTER FILE BACKUP F:\backup\distinationdirectory ZIP myzipfile.zip [DATE] END

c Save data file(s) etc. in a new encrypted data file, do not include current date in filename: AFTER FILE BACKUP F:\dist_dir ENCRYPT myencryptfile secretword END

(Points b and c copied from the help file for EpiData v3.1
