From the mail to info at epidata: if you change a qes-file in a relational database, epidata doesn't ask you to revise the rec-file if you open the file indirectly by the higher-level file, but only if you open it directly. cheers. mark

Good point. Relate is a very complex system. So to change structure of files in the middle of loading is a potentially error resulting situation. But I agree that the user should be warned somehow.

This should be added to the bug/problem reporting database - see link on www.epidata.dk
