Operating Instructions
hexadecimal, decimal, or binary, because ":A" is not valid for address
display.
The default is :0 :0.
3.6.1.5.3 Control Panel Commands
The following commands enable the VCP to perform the operations
of
a
control panel:
070-C
BOOT - Places VCP in auto-boot condition.
BOOT <number> - Boots with
sense
switches
set
to
"number".
"BOOT 114" bootstraps From a SMD, CMD, MMD, or FMD.
DISPLAY <address>
-
Displays
contents
of
"address".
This
command only operates when multi~user PRIMOS is running.
DISPLAYC <address>
-
Continuously
displays
contents'
of
"address".
The value is displayed each time it changes.
This
command only operates when multi-user PRIMOS
is
running.
To
end display, enter CONTROL~P.
FETCH - Fetches data according to the previously set sense
and
data switches.
LIGHTS - Displays the current lights...
LIGHTSC - Displays current lights continuously.
The lights are
displayed each
time
they
change.
To
end
display,
enter
CONTROL-P.
RCP <location> - Identical to RUN (see below), except that
the
vCP
stays in CP mode.
The "location" may be a virtual address
if the CPU is running in segmented mode.
RUN <location> - Clears the sense switches and places
the
CPU
in RUN mode at "location".
(This causes a problem when running
T&Ms. )
If
location
is not supplied, the current value of RP (program
counter) is used.
(After a
"SYSCLR",
the
current
value
is
1000.)
This
command
automatically puts the VCP in ST mode (see RCP).
SD <number> - Sets the DATA switches to the value
of
"number"
for one INA instruction only.
SS <number> - Sets the SENSE switches to the value of "number".
SSTEP <n> - Single steps
"n"
locations.
The
value
of
"n"
depends upon the data representation.
For example, if the data
specification is octal, "SSTEP 10" steps 8 locations.
STEPU <n> - Steps until address is equal to "n".
STORE <n> - Stores the value of "n" into the location specified
by the previously set sense and data switches.
