This post is out of curiosity.

I been tracing certain app that contains several 16 bit modules.
What arouse my curiosity is that I often find myself tracing through 16 bit code WITHIN the winXP kernel.dll. This is sort of unusual, and I thought all the latest (XP) Win code was 32bit.

Since win98 phased out I had not seen 16 bit code inside win system dlls.
Does anyone seen or have more info on this?

Are you sure this 16-bit code isn't just a thunk layer to the 32-bit code in order to provide backward compatibility?
