The tid is the thread identification.  The tib is the thread identification block.

 MB> DosCreateThread instead of _beginthread ?

They are similar functions.  DosCreateThread() is in the API.  _beginthread
is part of the Watcom library, and judging by the compiler you're using,
CSet/2 also.  However, in this case, I would suggest _beginthread() as it
saves a lot of hassle.  There seems to be more documentation available on
it, than on the DosCreateThread() function.

You have to kill the thread first.  Then you can wait for it to finish.
