Update:I should have put some references in- I found the proper constant using the object viewer in Visual Basic (I added a reference to the PowerPoint libs to a proj). If you DON'T have VB installed, and you are using Active State's install, then I would suggest using their web-based object browser. It's a file named, aptly enough, browser.html, and I found mine in -

c:\perl\html\site\win32\ole\browser

WOO HOO!!!

That did it. Thank you.

Update: Apologies for my outburst, but as you can tell cacharbe's response solved a problem that I had been very frustrated with. I couldn't seem to find the ppSaveAsHTML constant anywhere. There doesn't seem to be much around with regards to manipulating PowerPoint documents, so I thought I'd post the code that I eventually came up with. It runs as a CGI, and takes the file name as an argument. It converts Excel, Word or PowerPoint documents to HTML, and also converts PowerPoint slides to JPEG, since Netscape can't view the HTML that PowerPoint creates. A simple script can display these JPEGs. This code would be better if it determined file type from MIME, but that's for another day. Hope this helps someone someday.
