First, I do not wish to discourage you in programming a Logo interpreter,
but there is a very good Logo in the Public Domain, called PowerLOGO.
It may even be freeware. Its syntax deviates a bit from regular LOGO
(not toomuch and I am not even sure, because it's the only LOGO I've
ever used), but as far as I can judge it's definetly worth checking
out. It's on a Fishdisk.

Second, there were numerous tips for drawing a turtle, most of which
involved doing complex stuff, like opening hundreds B-) of screens.
Just do this:
Gr Write 2
DRAW_TOITLE[ANGLE,X,Y]
Gr Write 0
DRAW_TOITLE[ANGLE,X,Y]
...where draw_toitle is your routine to draw a triangle.
This technique is also used to get rubberbands and is shown in one of
the example files. There is one disadvantage; It will flicker.
