Sounds like I miss interpreted what you were saying....

I've never seen that before....normally I'd think this was a hash =20
assignment, however, if you initialize poem with "bob" before this =20
statement, then it does behave this way.

What is more interesting is that if you assign poem =3D "bobcat" and =20
issue the above command, you get the value "tomcat". So this looks =20
like a shortcut for string replacement although I've never used it =20
this way before.

If you try to issue the above assignment with poem not having been =20
assigned an initial string or assigned as a hash, you get:

undefined local variable or method `poem'

I'm going to investigate that a little further....thanks.
