Oh, and thanks to you too.  I think I knew .transmit and .filter existed but
I didn't see it when looking through the Doc and I never use that anyway.
Shame on me for assuming their nonexistance, sorry.

PS. funny thing, I went back to see section 6.1.3 Float Expressions where I
had checked on the current use of .t and there those all were.  Can't even
see what I look for anymore. :-(
