Dear Alan:

Your scrutiny is much appreciated.

OK, the documentation is not very clear on this but not
100% wrong either. What we meant by that was that

The /PZ and /PZ0 switches handles the confirmation-prompt-on-
a-directory which are related to the deletion of extra
file/directory in the destination (which is performed
by /Z, /ZY, and/or /CLONE operations).

If you do not say anything, the /PZ0 is assumed. When
you add /PZ, you will find a new series of confirming prompt
at the beginning of extra directory processing in the
destination.

That was what the documentation was meant to explain.
Let me give you an example:

Say you have the following directory tree in the target

\mydst\
+--\mychild1
| +--xxx
| +--yyy
|
+--\mycild2
| +--\grandson1
| +--\grandson2

and, the source directory \mysrc\ does not have any
of these mychild1\ and mychild2\ subdirectories in it.
Therefore, when you perform the following command,

XXCOPY \mysrc\ \mydst\ /CLONE /PZ

Then, the /PZ switch will generate a confirmation prompt
at mychild1\, mychild2\, mychild2\grandson1\ and
mychild2\grandson2\ as an extra-fine control of which
of the extra directories to be deleted or left alone.

/PZ0 (which is usually a default setting) will disable /PZ.


It's much easier to add /PZ with /CLONE operation and see
the prompt in the first place in order to appreciate /PZ0.
(to do so, make sure the destination directory has a few
"extra" directories).

Sorry, the cut-and-paste from the source file left a mess
there. A careless editing work...

The section should read

/ZX Ignores of the Environment Variable XXCOPYX
/ZX0 Enables the XXCOPYX settings. Good for /CLONE and /RMDIR.
The shortcut /CLONE and /RMDIR contain /ZE as a component.
e.g., /CLONE/ZX0 allows the use of XXCOPYX settings.
