Holymygoodness, does that bring back "odd" memories -- I once wrote a basic
Logo interpreter: in RSBasic! It had the turtle and basic drawing
(penup/pendown/etc.), variables (including list) and most math available -
and to draw a circle in that...
... well, let's just say "Took quite a while." ;-) [1]
But for what it was, it (to me, anyway) was rather impressive to my feeble
mind back then. I still have the feeble mind, however, it's much less to
impressionable nowadaze. ;-)
Laterz,

[1] Do the phrases "Watching grass grow" or "watching paint dry" mean
anything to you? ;-)
