In article <37592@netnews.upenn.edu> alex@eniac.seas.upenn.edu (Edmund Davis) writes: There is no automatic function for updating the many file when the related one-field changes. You must write a script more-or-less as follows: (Place it in the [Company]CompanyName field and set the Only if Modified flag) relate many([Company]CompanyName) $new:=[Company]CompanyName apply to selection([People];[People]Company := $new) Along the more or less lines, it's important to note that (unless it's one of the things that got changed with version 2.0) local variables ($<varname>) don't carry their definitions into APPLY TO SELECTION commands; try replacing $new above w/ NewCoName or something like that, to get better results. -- R David Francis francis@cis.ohio-state.edu
