Hey Sam. Determine the current path where the app is by using sys(2004). Store this in a sting and use it to open all of your tables and make other references.

lcPath = sys(2004)
dbpath = lcpath + "data\"

use dbpath + "trains" in 0
use dbpath + "tracks" in 0
use dbpath + "tickets" in 0

Then you never have to worry about which drive your app is on or the user has mapped.
