Subject: Re: attr_reader vs Objects and Attributes

Brian,
Thanks that helps.
The code I pasted was from the Thomas & Hunt manual, but maybe I took it 
out of context.
Their presentation of the associated values further confused me.
aSong.artist  » "Fleck"
aSong.name  » "Bicylops"
aSong.duration  » 260

Yes - I was thinking attr_accessor was some combination of
attr_reader, and attr_writer.
Thanks again, Mike
