You are correct. Also i know that this was the first edition so i 
thought maybe there was some differences between the version of ruby it 
was realsed for and this current release.

Never thought of this as a problem!
as always it's the simple things you over look that cause the problems.

visited the ruby online tutorial last night and found it great!!
but i  am wondering why when i tried doing something from either the 
pickaxe book or a online pdf the interactive shell wouldn't allow me to 
do the same things!

one was to create a def (still i'll check this out better another 
night).

thanks for the help so far and in the famous words of arnie I'll be 
back!

dave.
