2.5.3 CONTINUE Command
The
CONTINUE command
is:
C(CR)
If
the CPU clock
is
running, the CONTINUE command restarts execution of a halted program at the
address currently
in
the PC.
If
the CPU clock
is
not running because of a microcode break point or the CPU
is
in
the microstep mode,
the
CONTINUE command restarts the clock and the console remains
in
the console
I/O
mode.
2.5.4 DIRECTORY Command
The
DIRECTORY command
is:
DIR(CR)
This command prints the directory of tape cartridge that
is
either inserted into the default TU58 tape
drive or inserted into a specified
TU
58
tape drive,
as
shown
below:
»)DIR
Prints
the
directory
of
the
tape
inserted
in
the
default
TU58
drive.
»)DIR
DDn:
Prints
the
directory
of
the
tape
inserted
in
the
specified
TU58
drive
(DD
0:
0 r
DD
1 : ) .
NOTE
If
only one tape cartridge is inserted, then the DIR
command prints the directory
on
that tape. Howev-
er, if one tape cartridge
is
inserted into each TU58
tape drive, then the DIR command prints the direc-
tory of the tape in the default drive
001:.
2.5.5 EXAMINE and DEPOSIT Commands
The EXAMINE and
DEPOSIT commands are, respectively:
E/[(qualifier)](space)(address)(CR)
D/[(qualifier)](space)(address)(space)(data)(CR)
The EXAMINE
AND
DEPOSIT commands are explained together because their formats are similar.
Both commands require definition of the address space and size of the operand
in
addition to the address.
The EXAMINE command reads and the
DEPOSIT command writes
<data>
at
the <address> specified.
The address and data lengths used depend upon the qualifier or qualifiers specified with the command.
If
no
address qualifier
is
specified, the default
is
the last used address and data length; following another
EXAMINE or
DEPOSIT, the same address
as
that of the previous command
will
be used
as
the default.
If
no
data length qualifier
is
used (Table 2-6), the default for a physical or virtual
EXAMINE
or
DEPOSIT
is
whatever the data length
was
in
the previous EXAMINE or DEPOSIT.
The <address> information must be either a one-to-eight hexadecimal digit, a register address specifica-
tion (Table 2-4), or a symbolic address specification (Table
2-4).
The initial default
is
zero; however, the
default
is
unpredictable when the address space
is
changed.
