.Y. and .N. are FoxPro features I never knew existed.

I was working with .NULL. and wondered if .N. would work, when ?
ISNULL(.N.) returned .F., not an error. After a few minutes it struck
me, .N. == .F. therefore .Y. == .T.

I checked in FPW and in VFP. After all these years and I find I still
don't have a clue :-)
