DATE.yy/mm/dd.
Changes the current system date. Unlock the
console before entering this command (refer to
UNLOCK command).
yy Year; 00 through 99.
mm Month;
01
through
12.
dd Day;
01
through nn (nn is the number
of days in the month).
TIME.hh. m m.ss.
Changes the current system time. Unlock the
console before entering this command (refer to
UNLOCK command). "
hh Hour; 00 through 23.
mm Minute;

DEBUG.
Reverses the current set or clear condition of
debug mode. When debug mode is set, the
message DEBUG appears in the header of the left
screen display. Debug mode provides system
origin privileges to validated users and allows
modifications to be made to the running system.
Unlock the console before entering this command
(refer to UNLOCK command). Use of debug mode
is not commonly allowed in normal production
environment.
ENGR.
Reverses current setting of engineering mode.
When engineering mode is set, the message ENGR
appears in the header of the left screen display.
Engineering mode allows PP /hardware diagnostics
and FORMAT/FDP to be executed if the user has
system origm privileges. Unlock the console
before entering this command (refer to UNLOCK
command).
STEP.
Sets monitor in step mode. Setting monitor in
st~p mode stops all central memory I/O operations
and prevents the system from processing PP
requests when the next monitor function is
encountered. Pressing the spacebar releases the
present step and stops again for each subsequent
monitor function. If a DSD command is entered
while the system
is
in step mode and all PPs are
assigned, it is possible the request cannot be
satisfied.
In
that case, the screen(s) will blink
until you correct the condition by clearing the
entry.
When step mode is set, the message STEP appears
in the header of the left screen display. Unlock
the console before entering this command (refer
to UNLOCK command).
This command is generally used by the site analyst
for debugging purposes and should not be used in a
normal production environment. In addition, the
system may set step mode automatically upon
detection of a main power failure or abnormal
environmental condition (refer to SIC Register
Error Detection, appendix F).
STEP,xx.
or
STEP ,xx,b, v.
Sets step mode for monitor function xx.t The
second form of this command sets step mode for
monitor function xxt only when byte b of the
output register contains a specified value v. b can
be
1, 2, 3,
or
4
and the range for v is
0
through
7777
s.
Setting step mode for monitor function xx
may stop all central memory I/O operations and
prevent the system from processing PP requ'ests
when monitor function xx is encountered.
Pressing the spacebar releases the present step
and stops again at the next function xx. If a DSD
command is entered while the system is in step
mode and all PPs are assigned, it is possible the
request cannot be satisfied. In that case, the
screens will blink until you correct the condition
by clearing the entry.
When this mode is set, the message STEP followed
by function number xx appears in the header of
the left screen display. The console must be
unlocked before entry of this command is
permitted (refer to UNLOCK command).
This command is generally used only by the site
analyst for debugging purposes and should not be
used in a normal production environment. Do not
enter this command .unless specifically directed to
do so.
In
addition, do not enter this 'command if
the system has automatically set step mode
because of a power failure or abnormal
environmental condition (refer to SIC Register
Error Detection, appendix F).
n.STEP.
or
n.STEP,xx.
or
n.STEP,xx,b,v.
Sets monitor in step mode for control point n.
The second form of this command sets step mode
for monitor function xx.
t
The third form sets
steps mode for monitor function xx t only when
byte b of the output register contains a specified
value v. b can be 1, 2, 3, or 4 and the range for v
is
0 through
7777
s ..
These commands perform the
same function as STEP., and STEP,xx,b,v., except
only control point n is stepped. Other control
points may be affected depending on the operation
being performed at control point n. Only one
control point at a time can be placed in step
mode. If a DSD command is entered while the
system
is
in step mode and all PPs are assigned, it
is possible the request cannot be satisfied. In that
case, the screens will blink until you correct the
condition by clearing the entry.
When this mode is set, the message STEP
preceded by control point number n appears in the
header of the left screen display.
If
xx was
specified, it appears to the right of the STEP
message. The console must be unlocked before
entry of these commands is permitted (refer to
UNLOCK command).
t
Monitor functions are described in the NOS Systems Programmer's Instant.
