Escape-to-common-lisp

Escaping to Common Lisp

Example:
ACL2 !>:Q

There is essentially no Common Lisp escape feature in the lp (but see set-raw-mode). This is part of the price of purity. To execute a form in Common Lisp as opposed to ACL2, exit lp with :q, submit the desired forms to the Common Lisp read-eval-print loop, and reenter ACL2 with (lp).
