Re: Searching for paths
Chris,
are you trying to find out if Euphoria is installed or not?
If you are, then you might like to look at the directories in the PATH
symbol, looking for ex.exe *and* exw.exe in the same directory. Unless the
user has done some serious rearranging of the Euphoria directory structure,
you should find ex.exe in a EUPHORIA\BIN directory somewhere on the path.
