To get around some of the issues:
- Allow drive letters 0-9. Reserve 0 for the root file system. Drive 9
for a 'temporary' file system.
- Implement a CD command that would map to changing drive 9 to be the
default drive number with the 'ci''d relative to the current drive
number. Set the default drive number to 9 when used.
(It may be easier to look at drive 0 as current, and drive 9 as root).
This way people get their 'cd' commands yet the drive letter combos
still work. It also allows for sub-sub directories which I could see my
original concept having issues with. (You'ld have to issue something
along the lines of : ci1:=2:image.d64 to change drive 1 to image.d64
that's under drive 2... or some other strange syntax).
