Also, preserve and restore does that partly.. of course it dosen't allow you
to go back one command at a time. But stata gives you the ability to view
the commands and easily select them from the review window and in 10.1 to
send it to a do file (that I found very useful!).
Also, if you run commands from macro in excel.. it wont let you undo it. I
suppose all this still dosen't properly answer your question, but I suppose
it has something to do with the fact that for the undo to work stata will
have to save temp files after each command is issued to revert back with
undo.

Subject: Re: st: why no 'undo' option in Stata
On top of what Maarten has already said, let me add that you can have
two log files, one for recording screen output and one for commands
only open at any one time. An expedient place to tell Stata to open
those is the profile.do -h profile-. Just put
*********
log using C:/Users/`c(username)'/Documents/Stata/log/mydefaultlog, append
cmdlog using
C:/Users/`c(username)'/Documents/Stata/log/mydefaultcmdlog, append
*********
in there (construct a dir "Stata/log" in your Documents first), and
any changes are reversible if you refrain from overwriting dta files.
The command log can be used as a do-file to replicate anything you
have done in the past...
