Someone suggested how to implement 'cd -' as swd (see below) under 4DOS.
I tried it; it works and I went one step further and alias 'cd' so that
'cd -' will do the same as it does under UNIX.

Just place the following 2 lines in file XXXX and do alias /R XXXX under
4DOS and you're in business. It will work across drives.

swd	set _d1=%_cwd^popd^set _d2=%_cwd^*cdd %_d1^pushd %_d2^unset _d1 _d2
cd	iff "%1"=="-" then swd^elseiff "%1"=="" then *cd^else *pushd %1^endiff


One minor bug, it doesn't track where you're going when you change drive
without using 'cd' (ie. when you do 'e:' or 'c:' etc). Anyone one to fix
that too ?
