Bob,
Ok…when I said IBM used undocumented calls to the OS I meant the
letters 'OS' to mean Windows since we were taking about how OS/2 broke under
windows when Microsoft changed the undocumented calls.
So it appears that now we agree.

Don,
My understanding of the situation was not that IBM was using undocumented
calls, but actually loading the Windows executables into memory and patching
them with custom modifications needed to run under OS/2. When MS issued an
updated version of Windows, the wrong locations were being patched cause the
mirrors moved.
