141. Reset to ADFS
     ~~~~~~~~~~~~~
There are occasions when you may wish to enter the ADFS filing system,
without causing the disc drive to start up and look for a directory. You may
have an 'ordinary' DFS disc in drive 0, and wish to *MOUNT an ADFS disc in
drive 1. The behaviour of the ADFS in this situation does depend on the
*CONFIGURE DIR (or NODIR) option. However, regardless of this, you can select
ADFS without the drive starting up, by either pressing <Ctrl><F><Break>, or
by typing *FADFS . The ADFS is a bit hard going at first, but by jove it's
worth persisting!
