For example, in the function definition <p></p> <pre> square(x) = x * x </pre>x is the <a href="/formal+argument">formal argument</a> or "parameter", and in the call <p></p> <pre> y = square(3+4) </pre>3+4 is the <a href="/actual+argument">actual argument</a>. This will execute the function square with x having the value 7 and return the result 49. <p></p> There are many different conventions for passing arguments to functions and procedures including <a href="/call-by-value">call-by-value</a>, <a href="/call-by-name">call-by-name</a>, <a href="/call-by-reference">call-by-reference</a>, <a href="/call-by-need">call-by-need</a>. These affect whether the value of the argument is computed by the caller or the callee (the function) and whether the callee can modify the value of the argument as seen by the caller (if it is a variable). <p></p> Arguments to functions are usually, following mathematical notation, written in parentheses after the function name, separated by commas (but see <a href="/curried+function">curried function</a>). Arguments to a program are usually given after the command name, separated by spaces, e.g.: <p></p> <pre> cat myfile yourfile hisfile </pre>Here "cat" is the command and "myfile", "yourfile", and "hisfile" are the arguments. <p></p> <p class="updated">Last updated: <a href="/new.html">2006-05-27</a></p> <p></p> <p class="vertical-space"></p><h3>Nearby terms:</h3> <p class="neighbours"> <a href="/AREV">AREV</a> ♦ <a href="/AREXX">AREXX</a> ♦ <a href="/arg">arg</a> ♦ <b><a href="/argument">argument</a></b> ♦ <a href="/Argus">Argus</a> ♦ <a href="/Ariel">Ariel</a> ♦ <a href="/ARI+Service">ARI Service</a> ♦ <a href="/ARITH-MATIC">ARITH-MATIC</a> </p> <p> Try this search on <a href="https://www.wikipedia.org/wiki/Special:Search?search=argument">Wikipedia</a>, <a href="https://www.wiktionary.org/wiki/argument">Wiktionary</a>, <a href="https://www.google.com/search?q=define:argument">Google</a>, <a href="https://www.onelook.com/?w=argument">OneLook</a>. </p> <p class="vertical-space"></p> <hr> <div></div> <hr> <!-- if HTMLCOMMENTBOX --> <div id="HCB_comment_box">Loading</div> <link rel="stylesheet" type="text/css" href="//www.htmlcommentbox.com/static/skins/bootstrap/twitter-bootstrap.css?v=0"> <script language="javascript" id="hcb"> hcb_user = { PAGE: 'https://foldoc.org/argument', comments_header: ' ', no_comments_msg: ' ', err_comment_empty: 'Your comment was not posted because it was empty!', rss: '', }; var s = document.createElement("script"); s.setAttribute("type", "text/javascript"); s.setAttribute("src", "//www.htmlcommentbox.com/jread?page=" + escape(hcb_user.PAGE).replace(/\+/g, "%2B") + "&mod=%241%24wq1rdBcg%24.0y2uzvjA2bsnhzpXVq9F." + "&opts=17374&num=10"); // No e-mail field: 16846 if (typeof s != "undefined") document.getElementsByTagName("head")[0].appendChild(s); </script> <script> setTimeout(function () { document.getElementById('hcb_form_content').rows = 1 }, 1000); </script> <hr> <!-- end HTMLCOMMENTBOX --> </div> <!-- content --> </div> <!-- left --> <div id="right"> <div id="google_translate_element"> <script> function googleTranslateElementInit() { new google.translate.TranslateElement({ pageLanguage: 'en' }, 'google_translate_element'); } </script> <script src="https://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script> </div> <p><br></p> <hr> <div id="social"> <div class="fb-like" data-href="http://foldoc.org/" data-layout="button_count" data-action="like" data-show-faces="false" data-share="true"> </div> <a href="https://twitter.com/share" class="twitter-share-button" data-via="foldoc"> Tweet </a> <script> if (!document.getElementById('twitter-wjs')) { var fjs = document.getElementsByTagName('script')[0], js = document.createElement('script'); js.id = 'twitter-wjs'; js.src = 'https://platform.twitter.com/widgets.js'; fjs.parentNode.insertBefore(js, fjs); } </script> </div> <hr> <div> <p></p> </div> <p> <a href="/rss.xml"> <img src="/orangerss.gif" width="14" height="14" alt="RSS feed of new items"> </a> <a href="/new.html">Recent Updates</a> | <a href="/missing.html">Missing Terms</a> </p> <p>Updated: Sat, 05 Apr 2025 21:25:49 GMT</p> <p>15282 entries</p> <p><em><a href="/Free+On-line+Dictionary">Copyright Denis Howe 1985</a></em></p> </div> <!-- right --> </div> <!-- container --> <!-- Start Quantcast --> <script type="text/javascript"> window._qevents = window._qevents || []; (function() { var elem = document.createElement('script'); elem.src = 'https://secure.quantserve.com/quant.js'; elem.async = true; elem.type = 'text/javascript'; var scpt = document.getElementsByTagName('script')[0]; scpt.parentNode.insertBefore(elem, scpt); })(); window._qevents.push({ qacct: 'p-48Rosdvs3EiOc', uid: '__INSERT_EMAIL_HERE__' }); </script> <noscript> <div style="display:none;"> <img src="https//pixel.quantserve.com/pixel/p-48Rosdvs3EiOc.gif" border="0" height="1" width="1" alt="Quantcast"/> </div> </noscript> <!-- End Quantcast --> </body> </html>
