Path of loaded libraries

I dream about a Global Parameter containing the path of the currently loaded libraries. Useful for writing to macros from inside GDL, and checking the existence of a determined object inside the libraries.

Or shall it be a REQUEST function: nr=REQUEST("Loaded_Libraries_Paths","",path1, path2, path3, path4....)
Then if the user has multiple libraries loaded he can retrieve as many paths as he/she wishes....
