Re: [PVS-Help] Proving individual formula in batch mode

Hi Johannes,

There is a prove-formula function that takes a theory name, a formula
name and a rerun? flag.  If rerun? is t, it simply reruns the proof,
returning the proof state at the end.  You can check if it is proved by
checking if the status-flag is '!.  You can use your own variations of
the following definition, which also suppresses the usual prover output.

Sam Owre

(defun my-prove-formula (theoryname formname)
  (let ((*suppress-printing* t)
	(*printproofstate* nil)
	(*proving-tcc* t))
    (if (eq (status-flag (prove-formula theoryname formname t)) '!)
        (format t "~%Formula proved")
	(format t "~%Formula unproved"))))
