Cheers for that, Malcolm.
Are you saying that Si3C doesn't use "codes", then (CIVAB, nor any other) ... but just relies on a Model string?
How does it get on with our (oft-cited) "Dinamap" problem? In other words, how well does the system discriminate between different names (strings) for the same equipment?
I have also wondered about TBS-GB ... but have no information on that score (athough someone I knew there did once admit to using Ansur).
