  No. The function does not return PFNTHREAD.  The argument to
  DosCreateThread is a pointer to a thread function.  If you look at the
  type PFNTHREAD you will find that it indicates (or should indicate -- I
  don't know about the correctness of the VP headers, since I don't use
  Pascal) a pointer to function that takes a single 32-bit parameter and
  returns nothing.

  Incidentally, there may be Pascal runtime considerations that preclude
  calling DosCreateThread directly.  In C++, the C++ runtime has to be
  called (i.e.  _beginthread) when creating a thread in order that
  per-thread structures are properly managed within the runtime.  The
  Pascal runtime may require the same.  In which case, look to your Pascal
  library documentation on how to create threads.
