First, thanks to Michael Tsang for taking time to write and post these
programs.

Now, a suggestion: why doesn't somebody write a program that either (a) keeps
the directory stack in the environment, instead of having to have a writeable
file sitting around on disk and doing disk accesses for directory
pushing/popping?  Another approach would be a tiny program that gets the
current directory and then executes a fresh copy of command.com; when you
exit, the program would restore the current directory and then exit.  This
avoids scratch files and large environments, but takes up a few K of extra
ram for the fresh copy of the command interpreter.

Just some ideas...
