Thanks for the equations (I had in fact already worked those out), the
problem was
not that, the problem is that (as far as I am aware) LiveCode cannot
move objects
for fractions of pixels, so a move of , say, 30 forward at 30 degrees
might (and I haven't done
the Maths yet) either be 29, 30 or 32 units.
Whether, in the great scheme of things this is that important is not clear.

It is, as you said, going to need sin and cos. The X movement would be 30 *
cos(37/180 * Pi), and the Y movement would be 30 * sin(37/180 * Pi), in your
example case.

The problem is not with drawing the line.
The problem is how, when the turtle's "nose" is pointing at, say, 37 degrees
from the vertical
one can get it to move FORWARD for 30 units.

2.2. I wonder how my turtle will be seen to draw a pen line from the two ends of the
"line".
If you would like the “turtle” to move to the points of the line then, lock
screen, draw the line, hide the line and unlock the screen before you start
moving the “turtle”. Then no-one will ever see the line and you can delete last
graphic once the turtle has stopped moving.
