Thanks Alex. Your response enlightens me greatly, including to another possible piece of confusion I've got from this course. We have been told that you cannot import a SysDef committal into an existing IACC database. It can only be imported into a new database. If this was the case, then using SysDef would not be practical since one would have to edit SysDef and all IACC databases by hand whenever the System Definition changes (which seems to be every month here at LGL at the moment). Can you please clarify?
