I write functions for each case as manipulating indexes is a minor part only; except for building temporary databases you will have to check several conditions before you adjust an index and afterwards you may need to run some updating function like adding a new relation. For generic functions you may look at the Back End Upgrader (BEU) project but - as far as I understand - this does not handle the individual check/update of data. /gustav
