Good explanation Brett,
Most newcomers to rebol seem to pick up modifying
strings before modifying code blocks. What's so
difficult about modifying blocks of code?
The magic word is:
compose
I use this on a regular basis. Everyone needs
to know how it works. It is cool. It is also
necessary for composing your code blocks in a
clean way.
Although I am not really expecting it here on this
list, I don't see a script header. If you are not
using script headers, I recommend them to you and
anyone else reading. All my scripts have them.
You can see Rebol Technologies standard header here:
probe system/standard/script
I think the most important fields are:
Title, Date, Version, Author and Purpose.
