DWORD Commands
There are four basic forms for the DWORD commands:
DWORD cdword-address>
DWORD cdword
address> = cdword-value>
DWORD cdwordraddress>
TO cdword-address>
DWORD cdword-address>
TO <dword_address>
= cdword-value>
All of these commands can be used whether or not the user's program is running.
DWORD cdword-address>
Thisform
is used to examine and then possibly change one or more sequential
DWORD variables. When this command is invoked iECM-96 will display the
cdword-address>
symbolically if a valid symbol exists for that cdword-address>.
Whether or not the symbolic display occurs, iECM-96 will display the
cdword-address>
in hexadecimal notation, the value of the DWORD in the default
base and wait for an input from you. You can respond with a CARRIAGE-RETURN
character, an ESC character, or by enterin
a numeric value. A CARRIAGE-RE-
TURN will terminate the command. An ES 8 will result in the display of the next
sequential DWORD variable. If a numeric value is entered then the DWORD vari-
able will be set to this value and the iECM-96 will again wait for input. At this point
you can respond only with an ESC or CARRIAGE-RETURN.
As before, the ESC will
z@;i;hde
next sequential DWORD and the CARRIAGE-RETURN
WIII terminate the
DWORD cdword-address>
= cdword-value>
This form is used to set an individual DWORD variable without first checking its
current value. When invoked, this command sets the DWORD variable at
cdword-address>
to cdword-value>.
DWORD cdword-address>
TO cdword-address>
This form is used to display a region of memory as a sequence of DWORD vari-
ables. When this command is invoked, iECM-96 will start by displaying the current
default base and then a series of lines showing the contents of the selected memory
region. If a symbol exists in iECM-96's symbol table for the next cdword-address>
then this symbol will be displayed. Whether or not the symbolic display happens, the
next line will start with a hexadecimal display of the address of the next DWORD
variable to be displayed followed by the display of up to 16 bytes of memory as
DWORD variables in the default base. A new line will be started whenever 16 bytes
of memory have been displayed on the line or a valid symbol exists in iECM-96's
symbol table for the next cdword-address>
to be displayed. The command termi-
nates when all of the DWORD vanables in the selected range have been displayed.
During lengthy displays you can stop the output to the console by hitting the SPACE
bar. Display can be resumed by hitting the SPACE bar a second time. The com-
mand can be terminated by entering a carriage return.
DWORD cdword-address>
TO cdword-address>
= cdword-value>
This form is used to initialize a region of memory to the given cdword-value>.
Note
that this command will take a little over a millisecond (at 9600 baud) for each
DWORD loaded. This command can be terminated by entering a carriage return but
this leaves only part of the memory region initialized.
