REBOL Pop Mail

I Have a pop mail checker script for REBOL and it uses this to list the emails: messages: read pop://you-userid:[your-password--your-pop-server] foreach message messages [ msg: import-email message print [ "From: " first msg/from "Subject: " msg/subject ] ] And I was wondering how to have the user input like a number or something like that and it would show them like: From: [Email--Email--com] Subject: Subject Body: Message Body. Message Body. Please Help. Thanks.
