Win32s Information
Win32s is a package provided by Microsoft to implement a subset of
win32 api calls on Windows 3.1 machines. It is not widely used as
it used to be as Windows 3.1 is no longer widely used. Nevertheless,
it is available for those who need their 32 bit applications to run
on all platforms.
More information is available on the Web by using the search key Win32s.
Here are two sites from which this software can be downloaded.
