The p flag returned by the Files command is the "protected" bit I think, bit 6 of the ioFlAttrib field of the HFileInfo struct. The o flag is the "open" bit, bit 7 of the same field. Someone please correct me if I'm wrong. Nick Pilch nicky@cup.portal.com AppleLink: NICK.PILCH

The "o" is the Open bit, lit if the file is currently open. The "p" is the Protected bit, also known (does anyone know WHY?) as the "Bozo" bit, which, I believe, is not used these days for anything at all... |<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>| | David N.

The story I heard was this was meant to implement copy protection, and the "Bozo" name derived from someone's view of the effectiveness/usefulness of the scheme (having a bit anyone with a low-level file editor could unset to indicate copy protection).

Once, I heard that the Bozo bit is used for a touch of rudimentary copy protection, and that if it is set it prevents the item from being copied in the finder, thus protecting it from Bozos. I do not know whether this was ever true, and I don't care enough to see if it is true now. -- Mark Wilkins -- "According to our contract, at precisely midnight of the night of her greatest triumph, the party of the first part, (that's you), agrees to render up her soul, now and forevermore, to the party of the second part.

The "p" is >the Protected bit, also known (does anyone know WHY?) as the "Bozo" bit, Because the protection scheme is so ridicilously bad, only a bozo could've come up with it (this is actually true...).
