RE: st: Preserve vs Save
Hi,
When you save the file gets permanently changed.
With preserve you can undo all the changes you have made after making the
preserve command by the command restore.
However if you say preserve and then save the file. On reopening the restore
command will not work.

-preserve- is a temporary solution for within one session of stata.
-save- is a permanent solution that continues to exist after you close
stata.
-preserve is thus useful if you want to change the data just to do some
calculations but don't care enough for this changed data to store it
permanently, and after you're done with the computations move back to
your original data.
So in your case you probably don't want to -preserve- your data.
Hope this helps,
Maarten
