As I understand it, you are correct. The alternative shell WShell, however, is not as loose about the protection bits. If a file does not have "e" set, the it's not an executable. If a file doesn't have "w" set, you can't write to it. I see no point, in a single user OS, for read-protection. What use is a write-only file? -- _ |__ Alex Matulich /(+__> Unicorn Research Corp, 4621 N Landmark Dr, Orlando, FL 32817 //| \ UUCP: alex@bilver.uucp ...uunet!tarpit!bilver!alex ///__) bitnet: IN%"bilver!alex@uunet.uu.net"
