iECM-86 COMMANDS

resume the display by pressing the space bar a second time. You terminate the command by entering a carriage return.

5.4.6STRING Commands

There is only one form of the STRING command:

STRING byte_address

The line starts with a hexadecimal display of byte_address followed by the NUL-terminated ASCII string starting at that address. For long strings, only the first 60 characters are dis- played. When trailing characters are stripped, decimal points (.) are substituted for the first three characters stripped.

5.4.7PORT Commands

There are four forms for the PORT command:

PORT port_address

PORT port_address = byte_value

PORT port_address TO port_address

PORT port_address TO port_address = byte_value

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

PORT port_address This form is used to examine and then possibly change one or more sequential PORT variables. When this command is invoked, iECM- 86 displays the port_address in hexadecimal notation and the value of the PORT 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 PORT variable. If a numeric value is entered, the PORT 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 PORT and the carriage return terminates the command.

PORT port_address = byte_value

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

PORT port_address TO port_address

This form is used to display a series of PORT variables. When this command is invoked, iECM-86 starts by displaying the current
