I just tried the program HIDORAMA on the Jan. 1991 STart disk, which is
supposed to modify the attribute bytes so that you can set/unset the
Hidden, System, and Protect bits on files. It is erratic in
performance, since some hidden files vanish from the desktop and others
don't, but it appears to have scrambled some directories. After using
it one of my HD partitions vanished entirely, although it reappeared
after a reboot. Whether any permanent damage was done I can't say.
I suspect that HIDORAMA.PRG does not always find the right bits to
fiddle and that it is capable of doing damage. Until someone reports
the details of the situation, I recommend against using it.

Apparently, when a file has it's PROTECT bit set, it ignores both the HIDDEN and SYSTEM attribues, don't ask me why. I thought I had checked this before shipping the stupid thing off to Start, but I just tried it and it doesn't work. You can HIDE and SYSTEM files just fine, as long as they are not PROTECTED as well. I'm a little confused why this does this, but that's nothing new. As to why you got "scrambled directories" and "disappearing partitians"... Geez. I dunno. I've been using HOD for over a year now and haven't had any trouble. What TOS are you using? Damn, I HATE it when I look like an idiot, Greg "STOP staring at me!" Knauss

You will also find that a write protected program will not get run if it's hidden. That's fixed too. +----------------------------------------------------------------------------+ !
