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? ;-)
