iECM-86 COMMANDS
5
command terminates when all of the WORD variables in the selected
range have been displayed. During lengthy displays, you can stop the
output to the console by pressing the space bar. You can resume the
display by pressing the space bar a second time. You terminate the
command by entering a carriage return.
WORD word_address TO word_address = word_value
This form is used to initialize a region of memory to the given
word_value. Note that this command takes a little over a millisecond
(at 9600 baud) for each WORD loaded. You can terminate this
command by entering a carriage return, but terminating the command
leaves only part of the memory region initialized.
5.4.4 DWORD Commands
There are four basic forms for the DWORD commands:
DWORD
dword_address
DWORD
dword_address
=
dword_value
DWORD
dword_address
TO
dword_address
DWORD
dword_address
TO
dword_address
=
dword_value
All of these commands can be used whether or not the user’s program is running.
DWORD dword_address
This form is used to examine and then possibly change one or more
sequential DWORD variables. When this command is invoked,
iECM-86 displays the dword_address in hexadecimal notation and
the value of the DWORD in the default base, then waits for an input
from you. You can respond with a carriage return, an ESC, or a
numeric value. A carriage return terminates the command. An ESC
results in the display of the next sequential DWORD variable. If a
numeric value is entered, the DWORD variable is set to this value
and the iECM-86 again waits for input. At this point you can respond
only with an ESC or carriage return. As before, the ESC displays the
next sequential DWORD and the carriage return terminates the
command.
DWORD dword_address = dword_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 dword_address to dword_value.
DWORD dword_address TO dword_address
This form is used to display a region of memory as a sequence of
