Re: Can CGI Do this ???

I'd prefer comparing the changed values to the actual values in the file,
not the stored ones in any state holder or hidden fields. That would make
more sense in a generic way.

How do you know that the actual values in the file haven't been changed by
another user?  If you truly do want a read next changed operation, the only
real way to know is to compare to a saved copy of the data.  It could be in
some kind of session object, or you could have the client return the before
and after versions of the data, but I don't think you could compare to the
data file, as in 'Chain to the file to see if the record is different.  If
so, post these differences as changes"
