But it can. If you open a script and choose save, it will be saved to the same place. Or do you mean an executing script? There are indirect ways to find the name of the executing script. For example, in R-devel (to become 2.13.0 next month), you can do this:

cat("This file is ", getSrcFilename(function(){}, full=TRUE), "\n")

The getSrcFilename() function will be new in 2.13.0. You can do the same in earlier versions, but you need to program it yourself.
