Dear statalisters!

I have a question on how to organise my Stata files in such a way that I
can change the directory structure, or copy everything to a new place,
while double-clicking a do-file to run it still works. I am under
Windows XP, Stata 8.2.

Suppose a do-file in directory project dir\analysis\analysis1 contains
the lines

   capture log close
   log using "D:\project dir\analysis\analysis1\analysis1X.log", replace
   use "D:\project dir\data\data3\somedata.dta"

Now I want to be as flexible as possible and avoid absolute path names
at all. Since I have so many do-files (around 70), I am looking for a
solution where the path info is stored only in one place, and I use
references to this in my do-files, so that the above becomes

   log using "<analysis path>\analysis1\analysis1X.log", replace
   use "<data path>\data3\somedata.dta"

Preferably, the path info is stored somewhere in the project directory
itself, under the top level directory. If I decided to have "project
dir\old version\data\..." in a few months, I'd just have to change
"project dir\pathinfo" to adjust the paths.

I know about global variables, but my problem is that I don't know how
to define them from within the project directory, such that
double-clicking a do-file works.

Any ideas on how to accomplish this?

Thanks a lot,
Eva Poen
