[colorforth] More SEAForth questions

[Howerd <oakfords@xxxxxxxxxxxxxx>]

Hi Jeff,

Thanks for your lucid explanations. A couple more questions :

1. In the crawler code @p+ is used in the left hand column as the 
runtime part of a magenta variable, and in the right hand part ( run on 
the neighbour node ) as a port fetch.
Is this a typo, are they different colours, or is there some other 
explanation?

2. In the test code there is a sequence of R U L D commands which 
connect to various neighbours. Allowing for the inversion across each 
row and column, is the sequence that is used "special" in that it will 
crawl through each node once ( allowing for the spherical world that the 
processors live on )?

Regards

Howerd  8^)
