Know of any using 'ZM' (Z ip M aster) ? At the moment I am working on the ZipDll end and will make that just use the extra data given it - I have to work out how to supply the data in a way that allows - 1. setting data where none existed (easy) 2. setting data where other data exists (also easy - just append it) 3. removing existing data (do I only remove that IDed 'ZM'?) 4. adding more data (append/replace?) 5. replacing existing For the moment I think I will try just supplying a VCL routine to 'format' the data ready to use by the Dll.
