Serves as a placeholder for a command argument ''within a macro'' (if used outside of a macro, an error is issued). The argument that takes the place of &amp;&amp;arg is [[Passing a command argument to a macro#Multiple argument example|dynamically provided]] by the Client user. 

'''Syntax:'''

<p class="syntax">&amp;&amp;arg(''n'') </p>

where ''n'' is a numeric constant, or a [[Working with macro variables|macro variable]]. </span>

<span class="f_Para">Designed for commands that have multiple arguments, this function parses the blank-delimited, user-provided string to determine the replacement values for the </span><span class="f_Monospace">&amp;&amp;arg</span><span class="f_Para"> occurrences within the command. The first such value in the string replaces </span><span class="f_Monospace">&amp;&amp;arg(1)</span><span class="f_Para">, the second replaces </span><span class="f_Monospace">&amp;&amp;arg(2)</span><span class="f_Para">, and so on. </span>

<span class="f_Para">The </span><span class="f_Monospace">[[Passing a command argument to a macro#Using the &argstring variable|&amp;argstring]]</span><span class="f_Para"> variable is a placeholder designed for single-argument commands within a macro. </span>

<span class="f_Para">If a command takes a single argument, or you want to treat whatever is passed to the command as a single string (even if it contains blanks), use the </span><span class="f_Monospace">[[Passing a command argument to a macro#Using the &argstring variable|&amp;argstring]]</span><span class="f_Para"> variable instead of the </span><span class="f_Monospace">&amp;&amp;arg</span><span class="f_Para"> function. </span>
