Routine D collects all the necessary input for the variables M, N, and T (lines
D0002 through D0004) that define the x and y coordinates and angle
θ
of a new
system.
To respond to a prompt:
When you run the program, it will stop at each INPUT and prompt you for that

Å
again to cancel the INPUT prompt.
To display digits hidden by the prompt, press
