If one follows a simple set of rules (documented in the SDK and elsewhere),
the app will run in Standard or Enhanced mode.   The rules are the same for
any protected mode SW -- no segment arithmetic, dont use seg regs for
temporaries,  dont write off the end of segments, ...  You can even write
applications that run under 2.x and 3.0, all modes -- there are a number
of apps today that do that (MS Excel and WfW are 2 examples).
