There is a page in the EducationCentre (in D4 anyway) that details this. See
Dolphin Developers Guide/External Interfacing/External Field Types/Unions.
Basically you define the structure by giving offsets to all the fields with
the items in the union all being given the same offset. You just have to
make sure the offsets allow for the largest union member.
See TYPEDESC class>>defineFields for an example

All previous messages are kept as text files on my web site. You can either
read them in a text editor or download one of two Dolphin packages (Bill's
DSDN or my NewsBrowser). Attachments to the original message are not
included in the archive but I do keep copies of those - you have to mail me
if you want one.
