Please, please, please give us more information when you have a question. If you want a 'readline exactly like Common Lisp's 'read-line, you'll have to write it yourself. If you want specific features, tell us what they are. It's hard to help when we have to guess what you actually want.
Arc code can be terse; English shouldn't be unnecessarily so.
Hi zck
Yes, I mean read-line like common lisp.
As I'm only learning arc, it will be not easy to me to write it, but I will try as i will be more familiar with Arc.
I like arc as it's code is simpler than common-lisp and is more readable.
