odd or even page in margin note?

[Mark Summerfield]

Hi,

I would really like to be able to do this:

import @BookSetup
macro @MyNote{
    @OuterNote
        {
            @Case {
                oddpage @Yield lines
                else    @Yield rlines 
            }
        address@hidden note}
    }

but I don't know how (or if) it is possible to know whether I am on an
odd or even page.

Thanks!
