I think that there is a BCALLZ() type thing, at least under ION.  You have 
to remember taht romcalls on the 83+ have to do other things, including a 
rst somewhere.  If you did something like:

call z,bcallz_vputs

bcallz_vputs:
bcall(_vputs)
ret

it would do what you are looking for (I think) but would be somewhat less 
than efficient.
