getProp puzzle

[Mike Bonner]

The "of stack b" part, delineates where the pseudo property resides. Since
there is no getprop nSL of stack b, you get nothing back.  Better off to
create a function that takes an object reference as a parameter, and make
sure its in the message path so you can hit it from anywhere.
