31<H2>Description</H2>
32<P>Outputs a string. Internally, this function calls <a href="OS_VSNPrintf.html"><code>OS_VSNPrintf()</code></a>. Therefore the useable string format (string output format) is more restricted than it would be with <a href="OS_Printf.html"><code>OS_Printf()</code></a>. However, you can save on the code and stack overhead by using this function instead of <a href="OS_Printf.html"><code>OS_Printf()</code></a>.</P>
33<P>This function is compiled with weak symbols. Therefore, you can overwrite them with your own function definitions.</P>
34<P>The maximum string length that can be displayed is 255 characters. If a string with 256 or more characters is specified, all characters from the 256th character are ignored.</P>
35<P>This function is used for debugging. It will not be included in the final ROM version (<code>FINALROM</code>).</P>
