/
(slash)
is
a
separator
that
must
be
specified
after
the
filespaceid
if
path
name
components
are
specified.
The
slash
must
also
be
specified
between
path
name
components.
When
/
is
specified
as
a
single-character
path
name,
it
indicates
the
root
(top)
directory
of
the
currently-mounted
byte
file
system.
Note:
A
path
name
must
not
start
with
two
slashes
when
in
the
XEDIT
environment.
pathname_component
is
the
name
of
an
object
in
the
BFS
hierarchy.
A
path
name
component
may
be
1-255
characters
in
length.
The
slash
character
(/)
and
the
null
character
(X'00')
are
not
valid
within
a
path
name
component.
If
multiple
path
name
components
are
specified,
they
must
be
separated
by
slashes.
All
path
name
components
prior
to
the
last
one
specified
are
interpreted
as
directory
names
in
the
hierarchy.
The
last
path
name
component,
if
not
followed
by
a
slash,
may
or
may
not
be
a
directory.
When
the
last
path
name
component
is
followed
by
a
slash,
it
is
always
interpreted
as
a
directory.
Path
name
component
names
are
case
sensitive.
Usage
Notes
1.
A
byte
file
system
may
be
enrolled
in
the
same
file
pool
as
other
byte
file
systems
and
SFS
users.
2.
In
the
OpenExtensions
environment,
all
byte
file
systems
are
uniquely
identified
with
the
/../vmbfs:filepoolid:filespaceid
construct.
3.
Path
names
can
be
specified
in
several
ways:
v
When
the
first
character
of
the
path
name
is
not
a
slash,
the
path
name
is
known
as
a
relative
path
name.
The
search
for
the
file
starts
at
the
working
directory.
To
establish
the
working
directory,
use
the
OPENVM
SET
DIRECTORY
command
or
the
chdir
(BPX1CHD)
callable
service.
To
find
the
value
of
the
current
working
directory,
use
the
OPENVM
QUERY
DIRECTORY
command
or
the
getcwd
(BPX1GCW)
callable
service.
v
When
/../vmbfs:filepoolid:filespaceid
is
specified
at
the
start
of
a
path
name,
it
is
referred
to
as
a
fully
qualified
path
name.
The
file
is
searched
for
in
the
byte
file
system,
which
is
defined
as
file
space
filespaceid
in
file
pool
filepoolid.
The
byte
file
system
does
not
need
to
be
explicitly
mounted.
v
When
the
path
name
starts
with
a
slash
(but
not
/../vmbfs:filepoolid:filespaceid),
the
path
name
is
known
as
an
absolute
path
name.
The
search
for
the
file
starts
from
the
root
of
the
currently
mounted
byte
file
system.
The
root
directory
can
be
established
by
using
the
OPENVM
MOUNT
command
or
the
mount
(BPX1MNT)
callable
service,
or
by
the
POSIXINFO
FSROOT
statement
in
your
CP
directory
entry.
To
find
the
value
of
the
root
directory,
use
the
OPENVM
QUERY
MOUNT
command
or
the
uname
(BPX1UNA)
callable
service.

4.
The
entire
path
name
must
be
in
the
range
of
1-1023
characters.
Individual
path
name
components
cannot
exceed
255
characters.
All
characters
are
valid
within
a
path
name,
with
the
following
restrictions:
v
The
null
character
(X'00')
is
not
permitted
within
a
path
name.
v
A
slash
(/)
is
interpreted
as
the
delineator
of
a
path
name
component.
