As Steven correctly indicates, a while loop is the way to go, however, since both prompts offer a binary choice, you can encode a default option with no additional code, e.g.: (while (progn (initget "Yes No") (/= "No" (getkword "\nDo you want to continue with the next step? [Yes/No] <Yes>: ")) ) (initget 1 "Previous New") (if (= "Previous" (getkword "\nContinue after the Previous position or start at a New postition? [Previous/New] <New>: ")) (princ "\nUser selected Previous.") (princ "\nUser selected New.") ) )
