Many thanks to all of you who answered my questions.
Here's another one. I need to removed a number of variables and revise the .chk file to correspond to the .rec file. The easiest thing to do would be to make the changes in an editor (notepad, e.g.). The Epidata documentation says that a .chk file may not be more than 64K (I believe) if it is being created in an editor. The .chk file is now about 108K. Does this mean I can't make the changes in an editor?

2 I've discovered I need to delete a number of variables from the data file. This seems straightforward since I can simply delete them from the .qes file and they will be deleted from the .rec file. What happens to the .chk file when I open the new .rec file with deleted variables? Will Epidata revise the .chk file by deleting the checks for variables that no longer exist?
