The # symbol is what I was looking for.
Like I said, I am embarrassed that I couldn't remember the #. - I did know the @ symbol, but that is what I have now.
But, it used to be that there was a variable that would toggle between the modes.
@Rob - The way mine is set since install, once you give the initial point, any coordinates that you give will only go that far. If I start a line at 20,20 and simply type 0,0 / enter, it draws a line of 0 length. BUT, if I type #0,0 it will draw the other end of the line to the coordinates of 0,0.
