EXPLANATION OF PWD CONFIGURATION CHOICES

0) Show passworded directories to non-wheels?

NO means that PWD will not display DU or Directory Names for
directories to which a password has been assigned when the
WHEEL byte is reset. This is useful as a security measure on
multi-user systems like a Remote Access System.
YES means that the DU and Directory Names will always be
displayed, disregarding the WHEEL byte. Display of Passwords
is never allowed to non-privileged (Wheel reset) users.

1) Control display of DU with DUOK (non-wheel)?    NO

The DU part of the Named Directory is always included in the
display when the Wheel Byte is set. A YES response to this
question causes PWD to display DU to non-privileged users 
only if the DUOK flag in the Z3 Environment is set. Some
Remote Systems prefer to inhibit any reference to DU, using
only directory names.




2) EXCLUDE character for drive list is ....        ~
3) Range designator for drive list is .....        -

These characters are used in the PWD command tail in a drive
list expression, which may be an undelimited list of drive
letters. The RANGE DESIGNATOR is the character that separates
the first and last members of a range of drives, like B-H.
The EXCLUDE character inverts the logic for the rest of the
drive list, causing the named drives to be excluded from the
display. You may change these if you are more comfortable with
some other pair of characters. For example, one might prefer
a '-' for the EXCLUDE character and '.' (period) for range.


ABCDEFGHIJKLMNOP         is a drive permission vector.
++++++++____+___         Set them all '+' to enable display
                         of all possible NDR entries.
During execution, this vector is ANDed with the drive vector
from the Z3 extended environment (if it's present). Further,
the Maximum Drive from any Z3 environment is used to reset
bits in this vector for drives greater than the maximum.
