Thanks, discovered the can_revector_int21 too, which seemed to help...
Now tho, can't seem to return a cleared carry flag: if I temporarily put
ds_printf("CF=%x\n",REG(eflags)&&CF);
in int21() after my function call I can see
CF=0
so it's still clear, but by the time it gets back to dos its set, is
there anything I need to be aware of in order to preserve CF?
