Hi,

first of all thanks to all of you for your engagement to solve this 'mystery'.

Just one remark: please do not use 'Iterations = 50;'. If the coding works
properly Povray will produce an amount of data to choke a horse with.

As far as using "X" or "Y" without declaring it is concerned: I used Ingo's
original code - means vector and angle are not separated - with

#declare Axiom = "X";
#declare Rules = dictionary{
  ["X"] : "XFYFX+F+YFXFY-F-XFYFX",
  ["Y"] : "YFXFY-F-XFYFX+F+YFXFY"
}
and it works like a charm (see attachment).

Furthermore I used Ingo's original and added Push and Pop stacks and...
Povray again complained about (vertices).
Could it be that Povray hates LIFO arrays <grin>.

Can't wait until Ingo's 'muse with the glass eye' is kissing me - I AM cleanly
shaven.

Time to investigate further.

Regards
Droj
