you shouldn't need to change the mode, why do you want to switch to mode
since the pc has changed between the two exceptions, I assume several
int 21 take place in a row.
so, if you use cont at the second exception, you're stuck as for the
first one. So, you should use pass if you want the execution to be
correct (even the second time)
