Re: [Flashforth-devel] Elements of FlashForth tutorial

[Mikael N. <mik...@pp...>]

Some minor comments.

Chapter 8
The word (  a left parenthesis followed by a space  says disregard all 
following text until
the next right parenthesis OR END OF LINE in the input stream"

Table2
leave sets the loop counter to zero, not r@

Chapter12
The compiler word create makes a new dictionary entry using the next 
name in the input
stream and compiles the pointer value of the first free data space 
location of the current data space context.
When executed, the new dictionary entry returns the pointer value.

Is that clear or can it be said simpler ? /Mike

Chapter 12.3
The word 'of' is missing.

Thanks Peter for a really good basic tutorial.

I wonder if it could be converted to html and make it readable directly 
on the web.
