Using a text file that you have created (called DIRS.TXT) this
routine can quickly CD into any directory without you having
to specify the full path.

(Mind and not overload the table with entries please... will
slow down the old CPU)



For example, in file DIRS.TXT

You could have:

DUNE2
C:\GAMES\DUNE2
...
...
...
...



So whenever this was typed at the command line
CDQ DUNE2

The directory becomes C:\GAMES\DUNE2


You can have as many entries as you like.
