In scratch I can't see any way to name your scripts. Unless I am missing something it can't be done.
This makes the classic, beautiful and elegant Barry Newell's turtle confusion puzzle sheet - my favourite introduction to turtle graphics - far more difficult to implement
I love Barry's puzzles because they start simple and scale to complex in the most deliciously, elegant fashion. He does this by using the earlier shapes as building blocks for the later shapes
For instance once you can draw a square with the cat starting and finishing in the middle (a centre-gon) then variations are possible by drawing smaller squares or rotating the cat before drawing same size squares
The scratch code shows how to draw one centred square.
In other versions of logo (microworlds, mswlogo) once you have the code for the centred square as a named procedure which can accept variable inputs then you can re-use the code elegantly to draw more complex shapes.
This elegance is not possible in scratch.
However, I did manage to complete one of Barry's more advanced shapes in scratch (number 38) which is a centred square rotated 9 times
using this scratch code:
So, the epistemological issue here is using names to blackbox code in order to write more elegant (clean) solutions to more complex problems.
Also there's no turtle in the default animal shapes. Outrageous :-) I miss that turtle. Mitch, can't you put it back in.
