You should be able to do that, but...
- DOSBox is meant for games. No one cares about applications, so you won't get support (but there are some threads talking about clipper on this forum). Don't try to get any support, it will end in tears.
- There are other emulators able to run DOS, like dosemu, PCem and some others. Maybe they'll give you some advices.
- The best option for DOS applications is to virtualize the damn thing. VMWare or Virtualbox could do the trick.
- None of this options would give you a seamless integration with Windows (sharing data between your DOS and Windows applications).
- Also, you could buy a new computer and install DOS on it. It would be the best option for compatibility.
