The bottom four lines of the screen show the contents of the
memory locations indicated by the address at the left of each
line. These locations vary depending upon which command is
used.
Command
Descriptions
When the DEBUG monitor
is
displayed, you can enter one of the
following single-key commands.
Any value entered as
an
address or a quantity must be entered as a
hexadecimal number.
To cancel
an
incorrect command, press 00.
A (ASCII Modify)
Aaddress
Enter the above command line
to
modify address.
If
address is
displayed
in
the monitor, vertical bars appear around
it.
After you enter address, it and the current byte appear
in
the lower
left corner of the screen. To modify the byte, type the new ASCII
value and press:
•
(SPACE
BAR)
to modify the byte and move to the next address.
•
(ENTER)
to modify the byte and exit from the A command.
If you do not specify
address, TRSDOS uses the current "memory
modification address" (shown by the vertical bars).
Example:
AD004
(SPACE
BAR)
causes address D004
and
the current byte value to appear
in
the
lower left corner of the screen. TRSDOS allows you to enter the new
byte value. Then press
(SPACE
BAR)
to continue, or
(ENTER)
to end.
B (Move Block of Memory)
Bstarting address,destination address,number
of
bytes
Enter the above command line
to
move a block of memory from
starting address to destination address.
Always specify a non-zero number
of
bytes. If you enter number
of
bytes as
0,
TRSDOS moves a block of 65,535 bytes to destination
address,
causing the extended debugger
to
function improperly.
Example:
B3E04
t4E34
t
14E
(ENTER)
moves the 14E-byte block of memory from 3E04 to 4E34.
