Try

. capture cd Hannah

This will -cd- if possible and continue otherwise.

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

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.
