DISC SERVICE PROCESSOR (DSP)
OSP
is
an
on-line
interactive
utility
package
for
the
debugging
and
servicing
of
processors
and
other
files
under
IRIS.
Any
location
in
memory
or
any
file
on
disc
can
be
accessed
by
the
use
of
OSP.
The
system
manager
may
allow
limited
access
to
OSP
for
authorized
accounts
(see

USING
nsp
Unless
otherwise
noted,
a
<RETURN>
is
required
to
activate
the
command
string.
The
<RETURN>
is
not
shown
unless
it
is
the
only
command
required.
Any
command
which
follows
an
F,
G,
or
H command,
examines
and/or
modifies
data
and
operates
either
on
real
memory,
on
a
file,
or
on
a
disc
block.
Any
address
may
be
specified
as
a
byte
address
by
adding
a
hyphen
to
the
address.
For
example,
03025-
will
dump
bytes
starting
with
the
right-hand
byte
of
word
address
1412,
and
E17000-
will
allow
entry
of
bytes
sthrting
at
the
left-hand
byte
of
word
address
7400.
The
contents
of
any
byte
address
may
not
exceed
377
octal.
If
a
byte
address
is
given
when
an
enabled
driver
file
(i.e.,
$file)
is
selected,
then
that
byte
address
in
real
memory
is
referenced;
this
eliminates
the
need
to
select
real
memory
to
examine
the
driver's
buffers.

A

may
be

containing
a

<indicated
by

where
r
is
a

may
be
activated
only
after
executing
the
instruction
at
the
breakpoint
location
a
specified
number
of
