Applications can always have dialog boxes or command line options which
specify the use of a new environment variable. If a Windows application
modifes an environment variable it only modifes the environment for that
application. A problem might be encountered if you were developing
co-operting applications for which the user might wish to be using
a non-default ticket file.

I'm not sure I understand what you are thinking of. Can you think of an
example where it be useful? If you have a single variable whih points to a
directory how would the application know which file to use within the
directory?
