REAL Commands
There are four basic forms for the REAL commands:
REAL <real address>
REAL <real-address> = <real value>
REAL <real-address> TO ere&address>
REAL crealIaddress> TO <real-address> = <real-value>
All of these commands can be used whether or not the user's program is running.
REAL <real-address>
This .form is used to examine and then possibly change one or more sequential
REAL variables. When this command is invoked iECM-96 will display the
<real-address> symbolically if a valid symbol exists for that <real-address>.
Whether or not the symbolic display occurs, iECM-96 will display the
<real address> in hexadecimal notation, the value of the REAL 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
TURN will terminate the command. An ES 8
a numeric value. A CARRIAGE-RE-
will result in the display of the next
sequential REAL variable. If a numeric value is entered then the REAL variable 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 display
thhnTxt sequentral REAL and the CARRIAGE-RETURN WIII termrnate the com-
REAL <real address> = <real value>
This form is-used to set an indkidual REAL variable without first checking its current
value. When invoked, this command sets the REAL variable at <real-address> to
<real-value>.
REAL <real-address> TO <real-address>This form is used to display a region of
memory as a sequence of REAL variables. When this command is invoked, iECM-
96 will display 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 <real-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 REAL variable to be
displayed followed by the display of up to 16 bytes of memory as REAL 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
<real-address> to be displayed. The command terminates when all of the REAL
variables 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 re-
sumed by hitting the SPACE bar a second time. The command can be terminated by
entering a carriage return.
REAL <real-address> TO <real-address> = <real-value>
This form is used to initialize a region of memoryto the given <real-value>. Note
that this command will take a little over a millisecond (at 9600 baud) for each REAL
loaded. This command can be terminated by entering a carriage return but this
leaves only part of the memory region initialized.
