45<H2>Description</H2>
46<P>Adds two vectors, <code><em><strong>a</strong></em> + <em><strong>b</strong></em></code>, and places the result in <code><em><strong>ab</strong></em></code>.</P>
47<P>During a debug build, <code>VECAdd</code> is interpreted as <code>C_VECAdd</code>, which is a normal C language version. During a non-debug build for a Broadway processor, the paired-singles equivalent of this function, <code><font face="Courier New">PSVECAdd</font></code>, will be automatically substituted. You can also call each of <code>C_VECAdd/PSVECAdd</code> explicitly.</P>
