Years ago when I was doing my O-Levels, they introduced a calculator exam in maths that I took. It stated on the front of that paper that "approved calculators were allowed, but NOT slide rules". All we could ask was "what advantage does a slide rule have over a calculator other than you can draw a straight line with it?"
Never thought of using it to underline or make straight lines, I must admit.
The slide rule I used as school was my dad's old one which even had inches and centimetres marked down the opposite long edges (it was a 12" rule).
My brother, a doctor, when her was a student used to keep a 6" rule in his pocket as he could calculate things quicker with a slide rule than the others with a calculator.
Now I know why Tony Tebby's son wasn't allowed to use the calculator in his French essay...they wanted to see how straight he could draw, or how good he was at using a ruler. ;-)
No mention of banning QL Turtle Graphics to make the stright line I take it...PENDOWN:MOVE 50:PENUP (if I remember correctly, the turtle starts off facing rightward).
"Initially the turtle's pen is up and the turtle is pointing at 0 degrees, which is to the right-hand side of the window."
You could always insert a 'TURNTO 0' to ensure the turtle is pointing the right direction. (Plus a 'POINT x,y' to ensure it starts in the right place...)
