| + | If you have a run-away prover command (e.g. GRIND), you can type | ||
| + | ''C-c C-c'' (while in the *pvs* buffer), which will drop you into Lisp. | ||
| + | At the <rcl> prompt, type (''restore'') to get back to the previous | ||
| + | sequent. | ||
| + | |||
| + | If PVS has lost its mind, type ''M-x reset-pvs''. Note. During garbage | ||
| + | collection, this command will not engage immediately. | ||
