iECM-86 COMMANDS

5.4.2BYTE Commands

There are four forms for the BYTE commands:

BYTE byte_address

BYTE byte_address = byte_value

BYTE byte_address TO byte_address

BYTE byte_address TO byte_address = byte_value

All of these commands can be used whether or not the user’s program is running.

BYTE byte_address This form is used to examine and then possibly change one or more sequential BYTE variables. When this command is invoked, iECM- 86 displays the byte_address in hexadecimal notation and the value of the BYTE in the default base, then waits for an input from you.

You can respond with a carriage return character, an ESC character, or a numeric value. A carriage return terminates the command. An ESC results in the display of the next sequential BYTE variable. If a numeric value is entered, the BYTE 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 BYTE and the carriage return terminates the command.

BYTE byte_address = byte_value

This form is used to set an individual BYTE variable without first checking its current value. When invoked, this command sets the BYTE variable at byte_address to byte_value.

BYTE byte_address TO byte_address

This form is used to display a region of memory as a sequence of BYTE variables. When this command is invoked, iECM-86 starts by displaying the current default base and then a series of lines showing the contents of the selected memory region. The next line starts with a hexadecimal display of the address of the next BYTE variable to be displayed, followed by the display of up to 16 bytes of memory as BYTE variables in the default base. A new line start whenever 16 bytes of memory have been displayed on the line. The command terminates when all of the BYTE 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.
