iECM-86 COMMANDS
5
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.
