Whenever a Turbo program terminates, all active drives are reset to
inactive.  Is there a way to avoid this?  Given the following test
program:

program active_drives;
var
   vect : integer;   { just look at first 8 bits (drives) }
begin
   vect := BDOSHL($18);   { HL contains the 16-bit login vector }
   writeln(vect)
end.

If ran from A: with C: D: and F: active, the vector would return 45d
(00101101b [lo bit corresponds to A] with '0' indicating active and
'1' indicating active).  Running the program hereafter would display
1.  

How can a program be halted without the simulated warm boot?
