Watcom's, sorry I should have made that clear.

Ok, you are talking about the setup of parameters for a call of DPMI
301h/302h etc. Hrrrmmm, hardly seems much of a test as I would expect the
majority of the time would be in the real mode function or interrupt. Or is
this a measure of the efficiency of setting up parameters before a DPMI
call?

Still, that can be done.
