If I am in a directory, say C:data\scholar\Hannah, and I type

-cd Hannah-

I get an error message, as one might expect.

I am just learning to use .do files for the bulk of my analyses and data manipulations, a la Svend Juul's great book. I usually try to -cd- to the relevant project directory somewhere near the begining of a .do file, then open the data file.

But if I am *already in* that directory when I run the .do file, Stata gives the same sort of error:

cd Hannah
unable to change to Hannah
r(170);
end of do-file

Is there a way to cd on a conditional basis, such as "if I'm not already in the Hannah directory, then change to it"? Would this require using something like

if c(pwd) !=


Since all of my project files are nested under a single directory for research projects, I suppose I could always put in my do-files a -cd- to that directory before the -cd- to the particular project directory.
