[EpiData-list] Re: protecting formulas in check file?

You cannot protect the chk-file completely (e.g. against someone determined to change its contents), but you can protect it from accidental changes it by setting the read-only flag of the file (see "file attributes" of your operating system).

I have some coefficient values and equations in my chk file and I wondered if there was some way to protect them from being changed by another user down the road?

In other words, can I structure it so somone in the field can enter the data into the form but not manipulate, accidentally or otherwise, the chk file contents?
