Q.html -- ACL2 Version 6.3

## Q

quit ACL2 (type `:q`) -- reenter with `(lp)`

    Major Section:  OTHER

    Example:
    ACL2 !>:Q

The keyword command `:q` typed at the top-level of the ACL2 loop will terminate the loop and return control to the Common Lisp top-level (or, more precisely, to whatever program invoked `lp`). To reenter the ACL2 loop, execute `(acl2::lp)` in Common Lisp. You will be in the same state as you were when you exited with `:q`, unless during your stay in Common Lisp you messed the data structures representating the ACL2 state (including files, property lists, and single-threaded objects).

Unlike all other keyword commands, typing `:q` is not equivalent to invoking the function `q`. There is no function `q`.
