<h3>ACL2-PC::REMOVE-ABBREVIATIONS</h3>(primitive)
<code>   </code>remove one or more abbreviations
<pre>Major Section:  <a href="PROOF-CHECKER-COMMANDS.html">PROOF-CHECKER-COMMANDS</a>
</pre><p>


<pre>
Examples:
remove-abbreviations -- remove all abbreviations
(remove-abbreviations v w)
                     -- assuming that V and W currently abbreviate
                        terms, then they are ``removed'' in the
                        sense that they are no longer considered to
                        abbreviate those terms
<p>
General Forms:
(remove-abbreviations &amp;rest vars)
</pre>

If vars is not empty (i.e., not <code>nil</code>), remove the variables in <code>vars</code>
from the current list of abbreviations, in the sense that each
variable in <code>vars</code> will no longer abbreviate a term.<p>

<strong>Note:</strong>  The instruction fails if at least one of the arguments
fails to be a variable that abbreviates a term.<p>

See also the documentation for <code>add-abbreviation</code>, which contains a
discussion of abbreviations in general, and <code>show-abbreviations</code>.
