st: RE: using pwd in an if statement
I think there are three answers here.
First, use absolute not relative names.
should work so long as you can get there
from wherever you are (including being
there in the first place).
Second, you are on Windows, but use
forward slashes nevertheless. Stata will
interpret that for you when talking to
your OS. Otherwise, sooner or
later you will get bitten by the multiple
interpretation of backward slashes.
Third, -capture- is a command you might
want to learn about.
