Actually, I downloaded and installed a DirectX update in Nov. of 2007. So, it is strange that I was missing this DLL. Installing the latest DirectX update did solve this problem.
I should have initially done a web search for the DLL in question.
Re. searching the manual: I've had problems with this, because a few of the manual pages run on forever, and there is no way to search within a given manual page.
Thanks very much!
