Memory Modify
MM
Syntax:
MM <
Address> [<Data>]
Where:
<
Address>
is a16-bit hexadecimal number.
<
Data>
is an optional 8-bit hexadecimal number.
The MEMORY MODIFY command allows the contents of memory to be
examined and/or modified as 8-bit hexadecimal data. If the 8-bit data parameter
is present on the command line, the byte at memory location
<
Address>
is
replaced with
<
Data>
and the command is terminated. If not, D-Bug12 enters
the interactive memory modify mode. In the interactive mode, each byte is
displayed on a separate line following the data’s address. Once the MEMORY
MODIFY command has been entered, single-character subcommands are used
for the modification and verification of memory contents. These subcommands
have this format:
[<
Data>] <CR>
Optionally, update current location and
display the next location.
[<
Data>] </>
or
<=>
Optionally, update current location and
redisplay the current location.
[<
Data>] <^>
or
<->
Optionally, update current location and
display the previous location.
[<
Data>] <.>
Optionally, update current location and
exit MEMORY MODIFY.
With the exception of the carriage return, the subcommand must be separated
from any entered data with at least one space character. If an invalid
subcommand character is entered, an appropriate error message is issued and
the contents of the current memory location are redisplayed.
Restrictions:
