Sorry, but I accidentally phasered the web address to the article that talked about Ada, C, VADS, Apex, etc. Could someone please give me the pointer again? Thanks in advance. And while I'm at it, I downloaded the WHYADA PowerPoint presenta- tion from PAL and when I tried to open it, I got an error 30 from PowerPoint when I tried to open it. Anyone have a solution to this? I have emailed Dr Conn, but have not yet received a response. Mark ================================================================= Maj Mark A.
