Ron,

Unfortunately, OS() and OS(1) return DOS 5.00, and Windows 3.95 respectively on all Win32 platforms up to at least Win2K Pro. Further, the GetVersion() API call available in Win32s doesn't correctly report it either.

You might wander out to Rick Strahl's West Wind site. I believe that he has a free utility that will allow you to call a 32 bit dll from a 16 bit app. Using that you could call the GetVersionEx() function passing a string to it representing an OSVERSIONINFO structure. Once you do that, you can parse the value returned to get the major and minor version numbers.
