<body text=#000000 bgcolor="#FFFFFF">
<h2>SET-SAVED-OUTPUT</h2>save proof output for later display with <code>:</code><code><a href="PSO.html">pso</a></code> or <code>:</code><code><a href="PSO_bang_.html">pso!</a></code>
<pre>Major Section: <a href="OTHER.html">OTHER</a>
</pre><p>
<pre>
Examples:
(set-saved-output t t) ; save proof output for later, but inhibit it now
(set-saved-output :all t) ; same as the line above
:set-saved-output t t ; same as the two lines above
(set-saved-output t nil) ; save proof output for later, but print it now too
(set-saved-output nil t) ; do not save proof output, and print it now
(set-saved-output nil nil); do not save or inhibit output
(set-saved-output nil :normal) ; default: do not save output, and only
; inhibit proof-tree output
<p>
General Form:
(set-saved-output save-flg inhibit-flg)
</pre>
Parameter <code>save-flg</code> is <code>t</code> or <code>:all</code> to cause output to be saved for
later display using <code>pso</code> or <code>pso!</code>; see <a href="PSO.html">pso</a> and see <a href="PSO_bang_.html">pso!</a>, and see the
documentation for <a href="PROOF-CHECKER.html">proof-checker</a> commands of the same names. Set
<code>save-flg</code> to <code>nil</code> to turn off this feature; except, it always stays on
in proof-checker sessions entered with <code><a href="VERIFY.html">verify</a></code>. The other argument,
<code>inhibit-flg</code>, controls whether output should be inhibited when it is
created (normally, during a proof attempt). So a common combination is to
set both arguments to <code>t</code>, to indicate that output should be suppressed for
now but saved for printing with <code><a href="PSO.html">pso</a></code> or <code><a href="PSO_bang_.html">pso!</a></code>. The examples above
give a good summary of the functionality, including the meaning of values
<code>:all</code> and <code>:normal</code> for the first and second arguments (respectively).<p>
Saved output is cleared at the start of every event, and also at the start of
every <a href="PROOF-CHECKER.html">proof-checker</a> commands that invoke the prover. Note that
interactive <a href="PROOF-CHECKER.html">proof-checker</a> commands, that is, from a proof-checker
session entered with <code><a href="VERIFY.html">verify</a></code>, are always run with output saved.<p>
Also see <a href="SET-PRINT-CLAUSE-IDS.html">set-print-clause-ids</a>, which causes subgoal numbers to be printed
during proof attempts when output is inhibited.
