set work dir aliases (Any shell with aliases)

[Steve Tell]

Here's a similar scheme that several people have been using on both
csh and ksh:

csh:
alias	d1	'set D1=`pwd`'
alias	cd1	'cd $D1'

ksh:
alias -x d1="D1=\$PWD"
alias -x cd1="cd \$D1"

Typicaly, one has, say, d1 through d6.  I usually only use
two or three of them, and set them up so the numbers relate
to which is "primary" to the task at hand in some way.
Another usefull alias is one that prints the contents of $D1-$D6.
