It is absolutly possible to have mathematica sessions running while you are logged off. The point is that to achieve this easily you should indeed work in text-mode. This is not so difficult, you can mark the Cells to execute in your Notebook as Initialization-Cells and save the notebook. This should produce a .m file which you can then run from the command shell like this (on a tcsh): math < file.m > file.out & learn about the command shell you are using, you'll enjoy it! the < and > are redirecting stdin and stdout to files, the & will put the process to background. On some systems it might be necessary to call the process with a nohup or something, I only vaguely remember somthing like that from an old Sun workstation, but this depends on the setup, so ask your sys-admin. Of course it is important to save your results in a way you can further work with them, so maybe just reporting the output in a file.out is not what you want, have a look at Mathematica-command like Save, Put and DumpSave. I (and many others) have used mathematica in that way successfully in calculations that run for many days and even weeks. It works quite well, the only problem I have seen resulted from network-lossed when the files were served over NFS, so probably it's better to use a local filesystem (it's much faster anyway). If this sounds weird to you, learn about UNIX-filesystems :-). good luck Albert
