Are IBM and SCO 286 versions of Xenix binary compatible?

[Ray Curci]

Could some experienced XENIX guru tell me whether the binaries are
compatible between the IBM and SCO 80286 versions of Xenix?

I need to write some small programs (high level, nothing fancy, need only
stdio and curses).  I have access to an machine with IBM XENIX v1.0.
Can I simply compile my code under IBM XENIX v1.0 and copy the binaries
to be executed under SCO XENIX v2.3?   How abount binary compatibility
between SCO XENIX for PS/2 model 50  and  SCO XENIX for IBM ATs?
