RE: st: Help: Stata wont save a file!
As a "me too" to Ronán's comment, I recently took the Stata Netcourse NC151,
the opening lectures of which teaches you how to document your analysis
thoroughly using Stata's log function and do-files. Although it was a
pretty major shift for me in terms of working style, I am now a thorough
convert to the spirit of those methods. These include:
Having specific .do files for creating datasets distinct from those
producing analytical output (so you can always go back)
Having a "master.do" which is sort of a root program that steps through the
data creation and analysis steps with the other .do files as subroutines;
and most importantly, only entering a new .do in the list once you have
decided its purpose is achieved
Creating a profile.do and template.do files that take care of such tedium as
making a current directory (and a distinct directory!) for each analytical
project, initiating logs for each .do file run, turning -more- off and on,
I have multiple, concurrent, and divergent tasks for which I use Stata.
This system of documenting the analysis has allowed me to work much more
efficiently, and with a lot less re-learning when I return to a task I had
put aside (I just look at my .do files and logs in the directory which I
created the last time I worked the analysis.)
You still may lose work, but its much less painful when zipping through a
few, well commented .do files is all it takes to regenerate it.

One solution, in this case, would be to right-click the review window
and get Stata to save all the commands. Or, if Stata was in a wobbly
state, to save the commands to the clipboard and paste them into some
Ultimately, however, the solution is to build a do-file as you work.
Each time I make a significant addition to the do-file, I re-run it from
the beginning to make sure that the results are exactly as I thought.
All changes to the original data are commented, and any rationale that
needs explaining likewise. That way, if I should be bisected by the
tram, anyone can follow the progress of the data from raw file to final
dataset. I know this sounds goody-goody, but it is, as we say in Gaelic,
cíall ceannaithe (wisdom that came at a price).
