I was recently playing around with trying to unlock a file with the
file manager.  I was using PBGetCatInfo to go thru directories, so i 
thought i'd used PBSetCatInfo to set the file lock.  Seeing as how
the ioFlAttrib field will tell you if a file is locked, i figured i
could just turn off the locked bit and the do a PBSetCatInfo and the file
would then be unlocked. No such luck.  I ended up finding out about and
using PBRstFLock.

Why didn't the PBSetCatInfo call work?  What if i had wanted to change one
of the ioFlAttrib bits other than the locked bit.  What would i have been
able to do then?  Is there some little trick to using PBSetCatInfo for
this?

Thanx,
