You'd have to avoid using ANY files, and use INT 20h to end the program.
Either that, or encrypt your code, and then it would be difficult to locate
them from a straight disassembly.  (however, you'd still be able to see it in
a debugger, since you'd have to get it decrypted before you execute it.

No BIOS calls?  That could be even tougher, though I'm not certain that's 
hat
you're suggesting.

I don't think you'll find a high-level language to do this... most will be
reading the environment, or reading overlay files, or something that requires
int 21h.  One of the more common ones I've seen is version checking.  Also,
for floating-point emulation, they use int 21h function 35h to change Int 06.
