Users familiar with smalltalk, Common LISP Object System (clos), or other explanatory programming environments are certainly familiar with interactive development environments. Interaction Features allow you to experiment with small pieces of programming code. By using a special Ruby batch processing file IRB. bat, you can overcome the non-interactive features of the Ruby
