From the Sun386i User's Guide ( (c) sun microsystems, inc.) An early submission for your 'understatement of the year' contest: Page 143, 1st paragraph: "SunOS is based upon a UNIX operating system, and as such it allows broad freedom in selecting names for files. For example, a UNIX operating system file name can be up to 255 characters long. DOS file-name conventions, on the other hand, are somewhat more restrictive." :)
