1939 Register: column headings

[cati]

I've found Great Great Aunt Rose in an institution in the 1939 Register. 

Can anyone throw some light on the column headings?  Column 5 reads "O, V, S, P or I"  (Rose is recorded as I)

If you are using FindmyPast just scroll down below the search panel and the abbreviations are listed.

O – Officer
V – Visitor
S – Servant
P – Patient
I – Inmate

Ah, I was on Ancestry Pro (one of the online resources kindly provided by my local library).

That's exactly what I was expecting to find.  Many thanks!
