Hi: Since I use a Mac also, my answers should work for you. I believe the answer to your problem will be to append the folder containing your file to the $Path variable: $Path=Append[$Path, "HardDriveName:Folder:SubFolder"] The << command should work ok now. (I prefer to use the "Needs" command whenever possible.) >My questions: > -where should I have external files for Mathematica to see them? > _how to create a package, and where to store a newly created one for >Mathematica to see it. I have all my packages in a folder whose path is: "D. Penny:Mathematica:My Packages" Note that "D. Penny" is the name of my hard drive. The folder "My Packages"is a subfolder of the "Mathematica" folder. My init.m notebook contains the command: $Path=Join[$Path,{"D. Penny:Mathematica:My Packages"}] This allows any package in the folder "My Packages" to be seen by Mma. I suggest that you modify your "init.m" notebook as described above. This notebook is contained in the "Packages" subfolder of the "Mathematica" folder. Hope this helps. Cheers, Des Penny ========================== Des Penny Physical Science Dept.
