<a name="index-i960-callj-pseudo_002dopcode"></a>
<p>You can write <code>callj</code> to have the assembler or the linker determine
the most appropriate form of subroutine call: &lsquo;<samp>call</samp>&rsquo;,
&lsquo;<samp>bal</samp>&rsquo;, or &lsquo;<samp>calls</samp>&rsquo;.  If the assembly source contains
enough information&mdash;a &lsquo;<samp>.leafproc</samp>&rsquo; or &lsquo;<samp>.sysproc</samp>&rsquo; directive
defining the operand&mdash;then <code>as</code> translates the
<code>callj</code>; if not, it simply emits the <code>callj</code>, leaving it
for the linker to resolve.
