iECM-86 COMMANDS

WPORT wport_address = word_value

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

WPORT wport_address TO wport_address

This form is used to display a series of WPORT 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 ports. The next line starts with a hexadecimal display of the address of the next WPORT variable to be displayed, followed by the display of up to 16 WPORT variables in the default base. A new line starts whenever 16 bytes of memory have been displayed on the line. The command terminates when all of the WPORT 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.

WPORT wport_address TO wport_address = word_value

This form is used to initialize a set of ports to word_value. Note that this command takes a little over a millisecond (at 9600 baud) for each WPORT loaded. You can terminate this command by entering a carriage return, but terminating the command leaves only part of the memory region initialized.
