The thing about an env_var is that it is pretty much no different to an INI setting in this regard. By having the setting "closer" to the code using it (i.e. I see the location in the batch file used to run the testing, I see the location in the require_once() line in the main script), it is easier to see the location. An env_var or an ini setting is quite some distance away from the code and may seem "magical". What I'm not sure is how you can ever get away without explicitly declaring the location unless you always put the files in the include path. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
