Ed,
after I wrote back to Dave- just what you said occurred to me too. In some cases It might be nice to find out "how was I called" or from where (and thus reading the bear and not location 110).
And maybe the two (LBEAR and STBEAR) are just two flavors of the very same- one against memory and the other against a register.
But the final truth will be in the book. Martin
