How can I render the script?

Hello guys,

who can tell me how I can build a script in html site?I mean I want to render script into layout,like

<htmlb:content design="design2003" >

<script type="text/javascript" src="scripts/checkfunction.js"/>

I have CL_HTMLB_CONTENT,I can render it using print_string,but how about script?

Thanks in advance
