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. Stephen Howe
