Bernie,
I went around the block on this one a while back. The mnemonic for
today is CHSPARWED. ;-)

Does anybody want to add some more? Does Unix add more?
Don't know about your Icon questions. Have you got .info & disk.info
on the HD?

[The original message seems to have expired on our system, which is why I'm replying to this instead of the original...] In the current version of AmigaDOS, respect for the file protection bits is fairly spotty. Generally, OFS seems to ignore the protection bits most of the time, while FFS obeys them some of the time. In particular, WorkBench will not display icons on an FFS disk if it does not have read (R) permission to the *.info files, but it ignores the read bit on OFS disks. This is why the icons didn't appear on the hard disk but did appear on the floppy. -Dan Riley (riley@tcgould.tn.cornell.edu, cornell!batcomputer!riley) -Wilson Lab, Cornell University

Does it mean that the file has changed and should be added to the next archive (backup), or that the file has already been archived and no changes have been made since then? How about a less ambiguous designation, such as "touched"? All the other bits have fairly straightforward on/off, yes/no interpretations. Another stinker is warp. "WARP READ". Are you reading an archive to uncompress it to disk, or reading a disk to create an archive? A little forethought goes a long way. -- Jim Wright jwright@atanasoff.cs.iastate.edu

How about a less ambiguous designation, such as "touched"? All >the other bits have fairly straightforward on/off, yes/no interpretations. It is less ambiguous than you claim. The bit is "archived", so if set, it means "Yes this file is archived". Actually, "touched" would be the reverse of the sense of the "archived" bit. Backup utilities generally set the archived bit as a file is backed up. DOS clears the bit when the file is modified. By the way, the "C" (Comment) protection bit is not supported by Commodore. Perhaps somebody's "c:list" replacement shows a C if the file has a comment. The "H" bit is defined but not used. I have trouble finding a reference to "Hidden" anywhere. >-- >Jim Wright >jwright@atanasoff.cs.iastate.edu -- Peter Cherna, Software Engineer, Commodore-Amiga, Inc. {uunet|rutgers}!cbmvax!peter peter@cbmvax.cbm.commodore.com My opinions do not necessarily represent the opinions of my employer.

How about a less ambiguous designation, such as "touched"? All "Archived" is just as unambiguous as "touched". It means the file has been archived and not changed since then. As soon as a file is touched (opened for writing or updating) the "Archived" bit should be reset. Of course, until the OS actually supports those bits they don't mean anything at all. --Fabbian Dufoe 350 Ling-A-Mor Terrace South St. Petersburg, Florida 33705 813-823-2350 UUCP: ...uunet!pdn!jc3b21!fgd3

The OS (both the fast file system and the old file system) have supported the archive bit for a long time. (since 1.2) The fast file system supports the rw bits since 1.3 Both filesystems have always supported the delete bit. andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
